How far does the box go up the ramp before stopping ?

Question

A 3.9kg box is launched up a ramp (27.2 degrees from the horizontal) from a spring (k= 409.4 N/m) that was compressed by 0.7m.

How far does the box go up the ramp before stopping ? Assume the coefficient of friction is = 0.3

Answer 1

The PE in the spring becomes friction and PE of the box. If you want more help, contact me on WyzAnt.
