Starting from rest, a 4.10-kg block slides 2.6 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is ?k = 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 normal force.
