An 0.252 kg object is initially moving at 23.4 m/s [E] along the ice. The coefficient of kinetic friction for the object and the ice is 0.00500. a. What is the speed of the object after travelling 48.3 m?

b. Once the ice become rougher, the coefficient of kinetic friction increases to 0.0475. How far will the object travel if its initial and final speeds are the same as before?

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..

conservation of mass

mass before something happens = mass afterwards
