Answer:

1. If the mass and the momentum of an object are given, how do we find the value for its velocity?

a. v=m/p b. v= p/m c. v= p.m d. v= p=m

2. How does the value of the velocity of a person at rest affect his/her momentum?

a. A person at rest has constant velocity, therefore its momentum will also be constant..

b. A person at rest has no velocity, therefore its momentum will also be equal to zero.

c. A person at rest has no velocity, therefore its momentum will also be constant.

d. A person at rest has constant velocity, therefore its momentum will be equal to zero.

3. Which would be harder to stop, a rolling ball or an airplane taking off? Why?

a. An airplane that is taking off will be harder to stop since it possesses a greater mass.

b. An airplane that is taking off will be harder to stop since it possesses a greater velocity.

c. An airplane that is taking off will be harder to stop since it possesses a greater momentum.

d. A rolling ball will be harder to stop since it possesses a greater momentum.
