An ostrich has a mass of 135 kg. It is running with a velocity of 16.2 m/s north. What is its momen-tum? Show your work.

If we compare the force of gravity to strong nuclear force, we could conclude that

Why does it dangerous to jump from a moving vehicle?

An experiment was performed on a 2-kg block. forces of 5, 10 and 15 newtons respectively were applied to the block for 5 seconds. describe the difference in acceleration between the three trials. a) the final accelerations will all be the same. b) the final acceleration will triple between the first and third trial. c) the final acceleration will be cut by 1/3 from the first to third trial. d) the final acceleration will increase nine time between the first and third trial.
