Reference no: EM13510270

A 1.5 kg box slides down a frictionless incline of angle . It starts from rest at t=0 at the top of the incline at a height of 22 m above the ground.

1. What is the potential energy of the box relative to the ground at t=0?

2. What is the kinetic energy when it reaches the bottom of the incline?

3. What is the speed of the box then?
