Answer to Question #6502 in Mechanics | Relativity for Browe
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.
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.
I think I'm satisfied. I didn't really understand the last 2 projects you completed for me so i don't know if they were missing anything. I will note that the first 4 projects did contain small errors or did not incorporate all the instructions but these were easy fixes and helped with my learning experience. i will use your service again if the need ever arises.
