Question of the Day #20
Nov 4
A bus is initially traveling north at a constant velocity, as
shown. As the bus starts to make a left turn without changing
speed, a passenger notices that a box on the floor starts to
slide to the right side of the bus. Draw a free-body diagram
from a top view of the box that properly represents all of the
horizontal force(s) acting on the box. Label the force(s). Now
draw a free body diagram from a side view of the box.

Question of the Day #21
Nov 9
A force of magnitude F is applied to a crate on a
frictionless surface, as shown. A) This causes the crate to
slide in which direction? Explain.
B)The surface exerts a normal force of magnitude FN on
the crate before the force is applied. The crate remains in
contact with the surface the whole time. Does the crate
maintain a normal force equal to FN? Explain.

Block B hangs from a light string that passes over a light pulley
and is attached to block A, which is on a horizontal frictionless
table, as shown. Students are to determine the mass of block
A from the motion of the two-block system after it is released
from rest. What measurements must the students take in
order to determine the mass of block A?

This figure shows the forces exerted on a block that is sliding
on a horizontal surface: the gravitational force of 40N, the 40N
normal force exerted by the surface, and a frictional force to
the left. The coefficient of friction between the block and
surface is 0.20. What is the acceleration of the block?
