If you push a car with a force of 600 N on a level driveway for 15 m, how much work do you do on your car?

You go for a walk one afternoon down a level street to a park where there is a hill.  If the hill is 62 meters above street level and 4.6 km  from home , how much work in the physics sense do you do in order to get to the top of the hill?  Assume your mass is 65 kg and the acceleration of gravity is 9.8 m/s. Give your answer in joules (J).

You are out on the road with your friends, when you suddenly run out of gas. You and your friends apply a cumulative force of 103 N to push the car 96 m to the nearest gas station. What is the work done on the car?

A child pulls a sled upon snow covered hill. The child does 450 J of work on the sled. If child walks 12 m up the hill , how large a force must child exert ?
