1. A jeep with mass of 2000 kg is going 18 m/s at the bottom of a hill that is 50.0m high. When it reaches the top, it is travelling at 10m/s. (a) what is the total work done by all forces (the jeep engine, the mud, gravity, etc) as it ascends the hill? (b) What is the minimum work required by engine of the jeep if only the engine and gravity are doing work (if there is no friction, forces from mud, etc)?
