A 16.0 kg mass hangs on a string with a tension of 524 N. If it starts from rest, in what time in seconds will it be moving upwards at 58.0 m/s?

Match each scenario to the form of energy it represents

Acar weighs 15,000 n, and its tires are inflated to a pressure of 190kpa. how large is the area of the car's tires that are in contact with the road?

Consider lifting a box of mass m to a height h using two different methods: lifting the box directly or lifting the box using a pulley (as in the previous part). what is wd/wp, the ratio of the work done lifting the box directly to the work done lifting the box with a pulley?
