During a test crash, an airbag inflates to stop the dummy's motion. The dummy's mass is 75kg. The engineer knows the net force of the dummy was 825N. The engineer wants to know what the car's acceleration was What is the car's acceleration? What law of motion is demonstrated?

A1,200 kg car is accelerated at 3.7 m/s2. what force was needed to produce this acceleration? a. 4,440 n b. 324.3 n c. 4,388 n d. 304.3 n

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)

The amount of potential energy possessed by an elevated object is equal to what?
