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.
