Need serious help!!

1. How can the momentum of a moving object be found?
A. By multiplying its mass by its acceleration.
B. By dividing its change in distance trabeled by the time it travels.
C. By dividing its velocity bu the time it travels.
D. By multiplying its mass by its velocity.

2. In everyday life, changing the speed of a moving object will change all but which value?

B. Mass
C. Velocity
D. Momentum

3. What does Newton's second law of motion state?
A. For every force there is an equal and opposite force.
B. Momentum equals mass times velocity.
C. Force equals mass times acceleration.
D. An object at rest stays at rest and an object in motion stays in motion with the same speed and the same direction unless acted upon by an unbalanced force.

4. If the total net force on a system is zero, assuming the mass remains constant, which must be true?
