Calculate the final velocity of a child and sled at the bottom of a hill covered in snow if the mass of the child is 65 kg, the sled is 8 kg using energy calculations instead of the free-body diagrams and force analysis. The length of the hill is 1000 m and the slope is at 55 deg. angle. mus of k = 0.015.

Once at the bottom of the hill, how far must the sled travel in order to stop?

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 0.85 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 23.5 m and her speed at the bottom is 3.75 m/s, calculate the angle that the slope makes with the horizontal. slope...

A child is sitting on a sled and together they have a mass of 25.0 kg. The sled is being pulled by a rope which is angled 15 degrees from the slope. The sled is being pulled at a constant speed of 1.22 m/s up a 25.0 degrees hill that is 65.0 meters long. If the coefficient of friction between the sled and the snow is 0.180, what force is being used to pull the sled?

A 60.0-kg skier coasts up a snow-covered hill that makes an angle of 23.5 ° with the horizontal. The initial speed of the skier is 9.17 m/s. After coasting a distance of 1.45 m up the slope, the speed of the skier is 3.65 m/s. (a) Find the work done by the kinetic frictional force that acts on the skis. (b) What is the magnitude of the kinetic frictional force?
