Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

The slope of a velocity time graph over any interval of time gives the during that interval

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
