A skateboarder (m = 92 kg) takes a running jump onto a friend's skateboard that is initially at rest as sketched in the figure below. The friend is standing on the skateboard (mass of friend plus skateboard = 114 kg). After landing on the skateboard, the velocity of the board plus the two skateboarders is 2.8 m/s. What was the horizontal component of the velocity of the jumping skateboarder just before he landed on the skateboard?
