Question: A child slides down a snow-covered slope on a sled. At the top of the slope, her mother gives her a push to start

A child slides down a snow-covered slope on a sled. At the top of the slope, her mother gives her a push to start her off with a speed of 0.75 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 28.0 m and her speed at the bottom is 4.30 m/s, calculate the angle that the slope makes with the horizontal. 0 =
