Reference no: EM13530536

Starting from rest, a 5.5-kg block slides 3.00 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is µk = 0.436.

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

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

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