3 A block has an initial kinetic energy of 128J It slides up from point A at the bottom of the inclined plane with uniform deacceleration When it passes point B its Kinetic energy is reduced by 80J and its mechanical energy is reduced by 35J Calculate the work done against friction when the block moves from A to the highest point C on the inclined plane A 42J B 48J C 56J D 72J
