A 46.7 kg student runs down the sidewalk and jumps with a horizontal speed of 4.10 m/s onto a stationary skateboard. The student and skateboard move down the sidewalk with a speed of 3.86 m/s. a) Find the mass of the skateboard. Answer in units of kg b) How fast would the student have to jump to have a final speed of 6.54 m/s? Answer in units of m/s..

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 38.0-kg boy, riding a 1.50-kg skateboard at a velocity of 5.10 m/s across a level sidewalk, jumps forward to leap over a wall. Just after leaving contact with the board, the boy's velocity relative to the sidewalk is 6.00 m/s, 9.40° above the horizontal. Ignore any friction between the skateboard and the sidewalk. What is the skateboard's velocity relative to the sidewalk at this instant? Be sure to include the correct algebraic sign with your answer.

A diver (m = 60 kg) jumps from a diving board. At takeoff, his angular momentum about the transverse axis is 30 kg⋅m2/s. His radius of gyration about the transverse axis is 0.5 m at this instant. During the dive, he tucks and reduces his radius of gyrations about the transverse axis to 0.2 m. After he tucks the body, what is his angular velocity about the transverse axis?
