A block of mass 20 kg rests on a rough plane inclined at an angle of θ to the horizontal such that 7/25 sinθ=1.The coefficient of friction between the block and the plane is 0.2.
(i)Find the force, acting parallel to the plane, required to stop the block sliding down the plane.
(ii)Find the force, acting parallel to the plane, required to move the block up the plane.
