a child sleds down a 7.5m tall hill. the combined mass of the child and sled is 55.0kg. while sliding down the hill they encounter a 5.5m long rough patch of snow that exerts a friction force of 100N. if they had a speed of 1.4m/s at the top of the hill, what is their speed at the bottom of the hill? please be descriptive!!!

Two children are sliding down a snowy hill which is inclined by 47.7 degrees with respect to horizontal. One has a rough sled which has a coefficient of kinetic friction between it and the snow of μ​k= 0.371; the other has a slippery sled which has a coefficient of kinetic friction between it and the snow of μ​k​​ = 0.113. If both children start at the top of the 48.1 m tall hill initially at rest, what is the difference...

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...

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 dog sled is sliding down a hill. The sled starts from a height of 25 m and has a weight of 66 kg. It collides with a person at the bottom of the hill. The person weighs 72 kg. The collision is completely inelastic. Friction can be ignored due to icy conditions. Determine the speed of the sled and the person after the collision Show all steps for full marks.

Suppose the ski patrol lowers a rescue sled carrying an injured skiier, with a combined mass of 97.5 kg, down a 60.0° slope at constant speed. The coefficient of kinetic friction between the sled and the snow is 0.100. a) How much work in joules, is done by friction as the sled moves 3l m along the hill? b)How much work in joules, is done by the rope on the sled over this distance ? c) What is the work...

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 girl on a sled coasts down a hill. Her speed is 6.0 m/s when she reaches level ground at the bottom. The coefficient of kinetic friction between the sled's runners and the hard, icy snow is 0.052, and the girl and sled together weigh 688 N. How far does the sled travel on the level ground before coming to rest?
