Applying the equation learned, answer the following problems:
1. A bowling ball whose mass is 4.0 kg is rolling at a rate of 2.5 m/s. What is its momentum?
2. A skateboard is rolling at a velocity of 3.0 m/s with a momentum of 6.0 kg-m/s. What is its mass?
3. A pitcher throws a baseball with a mass of 0.5 kg and a momentum of 10 kg-m/s. What is its velocity?

Answers & Comments
1. mass = 4 kg
velocity = 2.5 m/s
momentum = mV
momentum = (4)(2.5)
Momentum = 10 kg- m/s
2. velocity = 3 m/s
momentum = 6 kg - m/s
momentum = mV
6 = m (3)
m= 2 kgs
3. mass = 0.5 kg
momentum = 10 kg- m/s
momentum = mV
10 = (0.5)(x)
V = 20 m/s
