You are given this problem:

A mass m slides down a frictionless track of radius R=0.5m. Relative to the center of curvature, what is the angular acceleration of the mass as it reaches the bottom of the track.

What principle would you use to solve the problem MOST
EFFICIENTLY.

- Kinematics only
- F = ma or Newton’s laws
- Work-Energy theorem
- Impulse-Momentum theorem
- Angular Impulse-Angular Momentum
- 1 & 2
- 1 & 3
- 2 & 3
- none of the above
- not enough information given
