Block m1 of mass 2 m and velocity v0 is traveling to the right (+x) and makes an elastic head-on collision with block m2 of mass m and velocity −2 v0 (i. e., traveling to the left). what is the velocity v1 ′ of block m1 after the collision?

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

scientific laws are the result of testing theories and proving them to be facts.
