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 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!!!

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?

You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15 m.

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
