A block with mass m = 16.1 kg slides down an inclined plane of slope angle 24.3o with a constant velocity. It is then projected up the same plane with an initial speed 3.35 m/s. How far up the incline will the block move before coming to rest?
= Kinetic energy.
Ep = m*g*h = 90.34
h = 90.34/m*g = 90.34/157.78 = 0.57 m
