A 150 gram block is projected up a ramp with an initial speed of 6.0 m/s. The coefficient of kinetic friction between the ramp and the block is 0.23.
(a) If the ramp is inclined 27 degree with the horizontal, obtain how far along the surface of the ramp does the block slide before coming to a stop?
m
(b) Find the minimum coefficient of static friction between the block and the ramp if the block is not to slide back down the ramp?
