Answer to Question #6502 in Mechanics | Relativity for Browe

Question

Freddy Frog drops vertically from a tree onto a horizontally moving skateboard. The skateboard slows. Give two reasons for this, one in terms of a horizontal friction force between Freddy’s feet and the skateboard, and one in terms of momentum conservation.

Answer 1

1. The larger is the mass of the body the bigger is the friction between 2 surfaces.
2. As the mass with frog is bigger than without it then the speed must be slower.
