In the picture at left. the launch height is 10m ball b mass 5kg has a launch velocity of 12 m/s and ball a mass 8 kg has a launch velocity twice that determine the time in flight for both the range for each and explain why the difference is masses is not considered

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?
