0.5 kg ball with a force of
50 N. What is the force
on the players foot?
A baseball player hits a ball
with a bat. What is the
action-reaction pair?
(2 answers!)
2 cars of different
masses collide. What
can be said about the
forces exerted on each?
A rocket is launched
upward with a force of
50N, it has an
acceleration of 25 m/s².
What is the rocket’s mass?
A hydraulic lift raises a
1000 kg car 2 meters off
the ground. What is the
cars potential energy?
What is the kinetic
energy of a 10 kg object
moving at a speed of
10 m/s?
A 0.20 kg bullet is fired
straight up with an initial
velocity of 300 m/s. What
is the maximum height it
can reach without air
resistance?
If Sarah has a mass of 40.0
kg and begins dropping
from 30.0 m above ground,
how much kinetic energy
will she have when she
reaches the ground?
If Kelly the skater’s
speed increases so she
has 3 times the
momentum, then her
kinetic energy increases
by…
When is linear
momentum conserved?
A child is on a sled moving
down a hill at 20 m/s. The
combined mass of child and
sled is 100 kg. What is the
momentum of the child and
sled?
A 70 kg skier leaves a ski
jump at a velocity of 14
m/s. What is the skier’s
momentum?
A cart with a mass of 1 kg traveling at
2 m/s catches up to another cart with
a mass of 2 kg traveling at 1 m/s. The
carts are moving in the same
direction. The first cart collides and
sticks to the second cart. How fast
are the carts moving as they are stuck
together?
Grace is bowling and only one pin
remains in her last frame. The pin
weighs 3 kg and Grace’s bowling
ball weighs 6 kg. If the ball is
thrown at 10 m/s, and after hitting
the pin it is moving at 5 m/s, how
fast is the pin moving after the
collision?
In which
direction will
the ball fly if
released at
the position
shown?
A car is driving around a
circular track, in which
direction must the
centripetal force act to
allow the car to stay
moving in a circle.
Draw a picture
of the
direction the
plane would
fly if the string
breaks.
What is the centripetal force
experienced by a 2000 kg
car traveling at a speed of
20 m/s while going around a
curve which has a radius of
50 m?

suddenly stopped acting
on the planets, how
would they move?

between 2 spheres is 100 N.
If the distance between them
is doubled, what is the force
between the masses?

between 2 spheres is 70 N.
If the distance between them
is halved, what is the force
between the spheres?

placed in boiling water.
How does the motion of
the noodle molecules
change, and why?
What is entropy?
A cup of boiling water at
100ºC is placed inside an
insulated box. The inside of
the box is 20ºC. Describe
the conditions inside the
box after a long period of
time.

heat energy of 10,750 J and
does 2420 J of work. What
is the heat lost in the
system?

reading compare with Monday’s
reading?
