Starting from rest a 430-kg block slides 200 m down a rough


Starting from rest, a 4.30-kg block slides 2.00 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.

(a) Determine the work done by the force of gravity.

(b) Determine the work done by the friction force between block and incline.

(c) Determine the work done by the normal force.

(d) Qualitatively, how would the answers change if a shorter ramp at a steeper angle were used to span the same vertical height?
