A 0. 500-kg ball traveling horizontally on a frictionless surface approaches a very massive stone at 20. 0 m/s perpendicular to wall and rebounds with 70. 0% of its initial kinetic energy. What is the magnitude of the change in momentum of the stone?.

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.
