A 1625 kg car, having run out of gas, is at rest on a level surface. Assuming an opposing frictional force of -765 kg m/s^2, if a person attempty to push the car due west by exterting a force of 765 kg m/2^2.

- If the person applies a force of 765 kg m/s^2 for 8 seconds, how much work did he do on the car?

- If he exerts a force of 2715 kg m/s^2 to get the car moving, what will be the acceleration of the car?
