A box of physics books slides down a ramp inclined at an angleof 40 degrees to the horizontal. The total length of the ramp is10m. The coefficient of kinetic friction between the box and theramp is .2 for the top 8m and zero for the bottom 2m. Upon reachingthe bottom of the ramp, a spring bounces the box back upward.
(a) Find the distance that the box travels back up the ramp onthe return bounce.
(b) Your answer shouldnt depend on the spring constant of thespring at the bottom. Why not?
