A (10 kg) block sits on top of an plane inclined by (32 degrees) to the horizontal. There is a coefficientof friction (μ= 0.1) between the block and the plane. The block is (4 m) above the ground when itbegins to slide down the ramp.(a) What is the normal force acting on the block?(b) What is the net force pulling the block along the plane?(c) What is the work done by gravity on the block as it moves to the ground?(d) What is the work done by friction on the block as it moves to the ground?(e) What is the speed of the block by the time it gets to the ground?
