Suppose you are swimming in the ocean and you see the fin of a great white shark appear in the water 150 feet away from you. You are 40 from the shore/safety and can swim at a maximum rate of 3 feet per second. The shark can swim at a frightening 35 feet per second. Will the shark be enjoying you as a tasty snack? Are you Meow Mix? While on vacation, you get out of your vehicle to explore the African wild. You didn't realize how far away from your vehicle you had ventured when suddenly you spot a lion about 200ft away from you. You immediately begin to run towards your car and the lion darts after you. If your car is 80 feet away from you and you can run at a maximum rate of 19ft/s and the lion can run at a speed of 70ft/s, will you make it to the car on time? Or will you be kitty food? Does Mr. Sapone Poop on You? Mr. Sapone duct taped you to a floor and put an inclined plane elevated at 45° at the base of your head. On that inclined plane 1.5m from the floor is a 10kg block of poop that is sliding down towards your face. The poop is the sort that doesn’t leave tread marks (i.e. it is frictionless). The principal walks in to observe the class and he’s not too happy about the situation. He begins peeling you off the floor but its going to take him 2 seconds to do so. Does the poop hit your face? Explain. Distance poop travels____ Final velocity of poop____ Acceleration of poop____ Time to slide down______ Draw in the components of weight. 1.5m 45° Does the alligator eat you? 50kg 25Kg One Direction CDs 2 meters 4 meters Mr. Sapone has you assist him with the following physics demonstration. He assures you that his knowledge of physics is beyond reproach and you will be safe in the following situation. You may have twice the mass of the box filled with garbage but it is placed at half your distance from the pivot point so it generates twice the torque allowing you to balance perfectly. Is there anything wrong with Mr. Sapone’s reasoning? Explain. CLIFF Interior Crocodile Alligator (song) Massless frictionless pulley 20kg 5kg 5kg What is the acceleration of the system?

Charge C is twice as far from charge B as charge A is. All charges have different magnitudes. For each of the following combinations of charge signs, determine whether it is possible for the net electric force on each charge due to the other two charges to be zero. ΣF on charge A A B C + A + B + C + A + B C + A B + C + A B C A + B + C A + B C A B + C - - - ΣF on charge B ΣF on charge C Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero Must be nonzero Possibly zero D1-QRT05: THREE CONDUCTING SPHERES—CHARGE Two conducting spheres rest on insulating stands. Sphere B is smaller than Sphere A. Both spheres are initially uncharged and they are touching. A third conducting sphere, C, has a positive charge. It is brought close to (but not touching) Sphere B as shown. (a) Is the net charge on Sphere A at this time (i) positive, (ii) negative, or (iii) zero? Explain your reasoning. Sphere A Sphere B Sphere C (b) Is the net charge on Sphere B at this time (i) positive, (ii) negative, or (iii) zero? Explain your reasoning. (c) Is the magnitude of the net charge on Sphere A (i) greater than, (ii) less than, or (iii) equal to the magnitude of the net charge on Sphere B? Explain your reasoning. Sphere B is now moved to the right so that it touches Sphere C. As a result of this move: (d) Does the magnitude of the net charge on Sphere A (i) increase, (ii) decrease, or (iii) remain the same? Explain your reasoning. (e) Does the magnitude of the net charge on Sphere C (i) increase, (ii) decrease, or (iii) remain the same? Explain your reasoning. Sphere A Sphere B Sphere C D1-QRT05: THREE CONDUCTING SPHERES—CHARGE Two conducting spheres rest on insulating stands. Sphere B is smaller than Sphere A. Both spheres are initially uncharged and they are touching. A third conducting sphere, C, has a positive charge. It is brought close to (but not touching) Sphere B as shown. (a) Is the net charge on Sphere A at this time (i) positive, (ii) negative, or (iii) zero? Explain C induces a negative charge on B, that is electrons will move from sphere A to sphere B to be closer to the positive charge on C, which induces a positive charge on A since it now has an electron deficiency. (b) Is the net charge on Sphere B at this time (i) positive, (ii) negative, or (iii) zero? Explain The Sphere C induces negative charge on B because electrons will move to be closer to C. (c) Is the magnitude of the net charge on Sphere A (i) greater than, (ii) less than, or (iii) equal to the magnitude of the net charge on Sphere B? Explain The magnitudes of the net charges on A & B must be equal since both were neutral to start and for each electron that moved from A to B a positive was left behind on A. Sphere B is now moved to the right so that it touches Sphere C. As a result of this move: (d) Does the magnitude of the net charge on Sphere A (i) increase, (ii) decrease, or (iii) remain the same? Explain your reasoning. There is no charge exchanged between spheres A and B when sphere B is moved. (e) Does the magnitude of the net charge on Sphere C (i) increase, (ii) decrease, or (iii) remain the same? Explain your reasoning.. Charge (electrons) moves from B to C resulting in a lower net positive charge on C. D1-QRT09: TWO CHARGES—FORCE ON EACH In each case shown below, two charges are fixed in place and are exerting forces on each other. For each case, draw a vector of appropriate length and direction representing the electric force acting on each charge due to the other charge. Draw the vector representing the force with the length proportional to the magnitude on the left charge above that charge; and draw the vector representing the force with the length proportional to the magnitude on the right charge below that charge (see the example). For each diagram, use the same scale as the example. +Q +Q (a) +2Q +Q (b) -2Q +Q (c) -Q +2Q (d) -2Q +2Q Example (e) -Q +2Q (f) -2Q +2Q “Cars don’t fly Dom!” Parking Garage Your 7m long car is parked on the roof of a parking garage that is 35m tall.

In the Epic movie speed a bad guy puts a bomb on a bus and rigs it so the bus must stay above 50mi/hr or the bomb detonates killing everyone on board. Unfortunately for the people on the bus the highway the authorities shuttled them on isn’t finished. Keanu Reeves decides to have Sanrda Bullock floor it and they leave the edge at 67mi/hr. [1] if the bus is traveling vertically can it make it to the other side. [2] Assuming the bus was a point particle and left the highway initially with only a horizontal component of motion. How far below the first side must the other side of the highway be in order to make the jump? [3] Assuming the bus was a point particle, what angle ramp would be necessary for the bus to make this jump? If the distance between the tires is 25 feet and the distance between the frame of the bus and ground 15inches, will the frame of the bus drag on the ground?
