Problem
A 4.0kg block is released from rest at the top of a 2.0m long inclined plane that makes an angle of 30∘ with the horizontal. The plane is rough and the coefficient of kinetic friction between the block and the surface is 0.20.
(i) Calculate the magnitude of the acceleration of the block along the plane.
(ii) Determine the speed of the block when it reaches the bottom of the incline.
(iii) Find the time taken by the block to travel the 2.0m distance down the plane.
