When the 35-kg boy jumps on the 9-kg skateboard, he has a horizontal velocity of 4 m/s while the skateboard velocity is -1 m/s (the skateboard velocity is negative, which means the boy and the skateboard are going on opposite directions. What is the velocity of the boy on the skateboard once he stays on it?

Two people are in bumper cars on opposite sides of a halfpipe, as shownbelow. Both are released from rest, and both bumper cars have a mass of 500 kg. The personin the red car, staring on the left side of the halfpipe, has a mass of 70 kg and starts 2 m abovethe bottom of the ramp. The person in the blue car, staring on the right side of the halfpipe,has a mass of 80 kg and starts 2.5 m above the bottom of the ramp. Upon colliding, the bumpercars bounce off one another.

The football player in the picture kicks the 1.5-lb ball with a velocity vA of 50 mph, as shown. The ball bounces off the turf, having a coefficient of restitution with the ball of 0.35, before landing a second time in mud, getting stuck there. Based on this: a) What will the rebound velocity, v’B, and angle be? b) How much less high will the ball bounce than it reached during the initial kick? c) What total distance will the ball travel?
