Forest UCM NLM Oscilations

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 [math]R[/math] and the skateboard has a mass [math]m[/math].

Note: because the skateboard is frictionless, its wheels are not going to turn.

Step 1: System

The skateboard of mass [math]m[/math] is the system.

Step 5: apply Netwon's 2nd Law
