Show hintHide hint
Think about mass and how fast the object is moving.
Question 2.
What is the formula for impulse?
Show hintHide hint
Remember what you apply over a period of time.
3Question 3.
What is the formula for momentum?
- p = mv
- p = m/v
- p = m + v

- True
- False
Show hintHide hint
Reflect on how forces act.
Question 5.
A 5 kg object is moving with a velocity of 10 m/s. It collides with a 10 kg object at rest. If they stick together, what is their final velocity?
Show hintHide hint
Set up your momentum equation before and after the collision.
Question 6.
