At sea world, a 900 kg polar bear slides down a wet slide inclined at an angle of 25.0 to the horizontal. the coefficient of friction between the bear and the slide is 0.0500. what frictional force impedes the bears motion down the slide?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
