1. A body of mass 30 grams is moving to the right with a velocity of 2 m/s. Another body twice as heavy is moving to the left with the same speed. What is the momentum of the system of two bodies?
2. A 1 kg body is dropped from the top of a tower. Find its momentum 2s after it is dropped.
3. What impulse is given to a 10 kg body by a force of 10N acting for exactly 1 minute.
4. A steel ball of mass 50 grams is dropped in a hard surface with a velocity of 5 m/s. If the ball rebounds with a velocity of 4 m/s, what is the impulse?
