1) A person wants to move a table from one side of the room to the other. The room is 15 meters across. If that person supplies a constant force of 500 N while pushing the table, how
much energy will it take them to move it?

2) A person pushed a shopping cart down an aísle at the grocery store. The entire time that person supplied a constant force of 10 N on the cart. That person did 200 J of work pushing it from one end of the aisle to the other. How long was the aisle?

3) A car is driving down the road. what type of energy is stored in the motion of the car?

4) A person has a mass of 85 kg and is in a building 75 meters high. what is the person’s gravitational potential energy? (g=10m/s^2)

5) A picture with a mass of 3 kg is sitting on a shelf. It’s gravitational potential energy 60 J. how high is the shelf?

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
