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 0.70 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 24.5 m and her speed at the bottom is 4.25 m/s, calculate the angle that the slope makes with the horizontal.

Problem 4 A child on a sled slides (starting from rest) down an icy slope that makes an angle of 15 with the horizontal. After sliding 20 m down the slope, the child enters a flat, slushy region, where she slides for 2.0s with a constant negative acceleration of -1.5 m/s with respect to her direction of motion. She then slides up another icy slope that makes a 20 angle with the horizontal. (a) How fast was the child going...

A 31 kg boy on a 4 kg sled is at the top of a slope that is 6 m high. He slides down the snow-covered, frictionless slope and across a road that is 8 m wide and then up a driveway at an angle of 15o. Both the road and the driveway have a coefficient of kinetic friction k = 0.36. How far does the boy slide up the driveway before he comes to a stop?
