Work done by friction: Wᶠ = f × d, force times distance.
Question 1 of 4
A model car going up an incline: mass 100 g, distance 39 m, force 0.063, work 2.457 J. Going down the incline: mass 70 g, distance 39 m, force 0.2309, work unknown. Work done by friction: Wf = f × d.
How much work done by friction was exerted on the car as it moved down the incline?
