A person is standing on and facing the front of a stationary skateboard while holding a construction brick. The mass of the person is 54.0 kg, the mass of the skateboard is 4.10 kg, and the mass of the brick is 2.50 kg. If the person throws the brick forward (in the direction they are facing) with a speed of 15.0 m/s relative to the skateboard and we ignore friction, determine the recoil speed of the person and the skateboard....

Dan is gliding on his skateboard at 2.36 m/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 8.02 m/s (as measured by an observer on the ground). Dan's mass is 60.1 kg and the skateboard's mass is 4.79 kg . If the jump requires 0.122 s to complete, what average force did the skateboard exert on dan?

A dog (mass 20kg) is running at 8 m/s toward a stationary skateboard (mass 2kg). When the dog reaches the skateboard, it jumps on. The dog and skateboard forward together without friction until they reach a ramp (30 degrees above horizontal). If the coefficient of kinetic friction between the ramp and the skateboard is 0.3, what is the maximum height the skateboard can reach?
