The 5-kg collar has a velocity of 5 m> s to the right when it is at a. it then travels down along the smooth guide. determine the speed of the collar when it reaches point b, which is located just before the end of the curved portion of the rod. the spring has an unstretched length of 100 mm and b is located just before the end of the curved portion of the rod.

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..

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
