You are given this problem:

A block sits on an incline with friction. Given the height of the block, the angle of incline, the coefficient of kinetic friction, and that block starts from rest, find the speed at the bottom of the incline.

What principle(s) would you use to solve the problem MOST EFFICIENTLY?

  1. Kinematics only
  2. F = ma or Newton’s laws
  3. Work-Energy theorem
  4. Impulse-Momentum theorem
  5. Angular Impulse-Angular Momentum
  6. 1 & 2
  7. 1 & 3
  8. 2 & 3
  9. none of the above
  10. Not enough information given
