Question

Worked Example: A 60 newton force moved an 8 kg object through a distance of 24 meters in 4 seconds. The frictional force opposing the motion was 36 N. (a) How much work was done by the 60 N force? What was the power? (b) How much energy was used to overcome friction? (c) What is the velocity of the object at the end of 4 seconds?
