Suppose you went bowling without a bowling ball and had only a softball and a large plastic ball to hit the pins. How would the speed and motion of these objects be different from when you use a heavy bowling ball? (Make sure you give an answer in complete sentence(s) and use your science vocabulary.)

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
