Starting from rest a 550-kg block slides 200 m down a rough, Ask an Expert

Academics

Starting from rest, a 5.50-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.

1. Determine the work done by the friction force between block and incline

2. Determine the work done by the normal force.

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