A 0.5 kg air puck moves to the right at 3 m/s, colliding with a 1.5 kg air puck that is moving to the left at 1.5 m/s
1) Determine the direction and speed of the pucks' motion if they stick to each other after the collision
2) Suppose instead that the pucks do not stick together. If the 1.5 kg puck moves to the right at .231 m/s after the collision, was the collision elastic? Provide evidence!
3) Determine the size and direction of the average force acting on the 0.5 kg puck during the second collision, if the collision lasted for 25 ms
