Achild slides down a snow-covered slope on a sled. at the top of the hill, her mother gives her a push to start her off with a speed of 1.00 m/s . the frictional force acting on the sled is one-fifth of the combined weight of the child and the sled. if she travels for a distance of 25.0 m and her speed at the bottom is 4.00 m/s , calculate the angle that the hill makes with the horizontal.
