1. In the diagram
below, a 100-kilogram clown is fired from a 500 kilogram cannon.

If the clown's speed is 15 meters per second after the firing, then the
recoil speed (v) of the cannon is

Answer:

2. The diagram shows a compressed spring between
two carts initially at rest on a horizontal frictionless surface.

Cart A has a mass of 2
kilograms and cart B has a mass of 1 kilogram. A string holds the carts
together.

Compare the carts inertia

Compare the carts momentum

Compare the force on each car when they
are pushed apart

Compare the impulse on each car when they
are pushed apart

a)

b)

c)

d)

3.
The diagram below shows two carts that were initially at rest on a
horizontal, frictionless surface being pushed apart when a compressed spring
attached to one of the carts is released. Cart A has a mass of 3.0 kilograms
and cart B has a mass of 5.0 kilograms.

If the speed of cart A is 0.33 meter per second after the spring is
released, what is the
approximate speed of cart B after the spring is released?

4. A 1.2-kilogram block and a 1.8-kilogram block are initially
at rest on a frictionless, horizontal surface. When a compressed spring between
the blocks is released, the 1.8-kilogram block moves to the right at 2.0 meters
per second, as shown.

What is the speed of the 1.2-kilogram block after the spring
is released?

Answer

Momentum is conserved
in a closed system. (Total
Momentum before = Total Momentum _____)

Answer

A wooden block is at rest on a horizontal steel
surface. If a 10. Newton force applied parallel to
the surface is required to set the block in motion,
how much force is required to keep the block
moving at constant velocity?

(1) less than 10. N
(2) greater than 10. N
(3) 10. N

Answer

If the speed of a moving object is doubled,
