Problem
A block of mass 2kg is released from rest at the top of a 4m long rough incline making an angle of 30∘ with the horizontal. The coefficient of kinetic friction between the block and the plane is 0.20.
(a) Find the magnitude of the acceleration of the block down the incline.
(b) Calculate the time taken by the block to reach the bottom of the incline.
