Starting from rest, a 5.40kg block slides 3.00 m down a rough 30.0\" incline. The coefficient of kinetic friction between the block and the incline is pk: 0.436. (a) Determine the work done by the force of gravity. J (b) Determine the work done by the friction force between block and incline. J (c) Determine the work done by the normal force. J (d) Gualitatively, how would the answers change if a shorter ramp at a steeper angle were used to span the same vertical height
