    How do I solve these problems
    I don't want anyone to tell me the answer, but I need help deciding on which physics formula I should use. There are two questions: 1. You have the grand idea that the science building would be better situated if you moved it North by 4 meters. To accomplish this you go outside and push with a 200 N against the science building for 3 hours. Needless to say, the building does not move, but you have worked up a good sweat. How much work have you done? 2. A truck is trying to pull a heavy trailer. The truck pulls with a force of 10,000 N for 60 seconds, but is unable to move the trailer even a small distance. How much work does the truck do on the trailer?

    As I responded to your previous post yesterday - the formula to use is Work = force applied times distance moved. So what do you get for answers to these two questions?
