13.

What is the momentum of a 15-kg rock falling at 3 m/s?

5 kg m/s

18 kg m/s

45 kg m/s

A bowling ball has 9 kg m/s of momentum when it is rolled 6 m/s. What is the mass of the bowling ball?

54kg

15kg

3kg

1.5kg

15.

T or F: a semi truck and a motorcycle can have the same momentum

True

False

16.

What is Newton's Law of Conservation of Momentum?

Object in motion stays in motion and an object at rest stays at rest unless acted on by a outside force

Force = mass x acceleration

For every action there is an equal and opposite reaction

Momentum can not be created or destroyed without outside forces
