Problem
A block of mass 5kg starts sliding from rest from the top of a rough incline 4.0m long which is fixed at 30∘ to the horizontal. The coefficient of kinetic friction between the block and the plane is 0.20.
(i) Calculate the acceleration of the block while it moves down the plane.
(ii) Find the time taken by the block to reach the bottom of the incline.
(iii) Determine the speed of the block on reaching the bottom.
