1. A 2 kg object moves at 3 m/s. What is its momentum?
p = mass × velocity
p = 2 kg × 3 m/s = 6 kg·m/s
2. Which of the following increases an object’s momentum?
Momentum = mass × velocity
3. An object has zero velocity. What is its momentum?
4. A 2kg ball initially at rest is kicked and reaches a velocity of 8m/s. What is the change in momentum (impulse)?
5. A 2 kg object moves to the right at 4 m/s. A 3 kg object moves left at 2 m/s. What is the total momentum?
6.A 4 kg cart moving at 3 m/s collides elastically with another 4 kg cart at rest. What are their velocities after the collision?
7.Two carts collide and stick together after the collision. What kind of collision is this?
8.A 2 kg cart moving at 3 m/s hits and sticks to a 1 kg cart at rest. What is their final velocity?
