Solve the all parts of following question:
Question: Starting from rest, a 2.05 kg block slides 2.86 m down a rough 32.9o incline. The coefficient of kinetic friction between the block and the incline is 0.422. The acceleration of gravity is 9.8 m/s2.
Part A: Find the work done by the force of gravity.
Part B: Find the work done by the friction force between block and incline.
Part C: Find the work done by the normal force.
I need help to find the work done by the friction force between block and incline.
