A crate is given an initial speed of 4.0 m/s up the 29.0 ∘ plane shown in (Figure 1). Assume μk = 0.12. How far up the plane will it go? How much time elapses before it returns to its starting point?
Homework Answers
While going up, kinetic energy is converted into potential energy but some energy is lost due to friction
ANSWER: 
===============
Going Up
Initial speed , u =4m/s
final speed ,v =0m/s
Use formula 
to find deceleration
Use formula 
, to
find time
==============
Coming down
