Skate boarder in Half pipe
Consider a frictionless skateboard released from the top of a semi-circle (half pipe) and oriented to fall directly towards the bottom. The semi-circle has a radius and the skateboard has a mass .
Note: because the skateboard is frictionless, its wheels are not going to turn.
Step 1: System
The skateboard of mass is the system.
Step 1: Coordinate system
Polar coordinate may be a good coordinate system to use since the skateboard's motion will be along the half circle.
