Two masses, m1 = 1.8 kg and m2 = 1.3 kg, are ar on a track set at a 25 degree incline. they are attached by a string passing over a pulley. the system is released and the masses travel a distance h = 1.0 at a constant speed. what is the work generated by friction?

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..

cant without the picture! ?
