A sled and rider with a combined weight of 69 kg are at rest on the top of a hill 15 m high.

(a) What is their total energy at the top of the hill?


(b) Assuming there is no friction, what would the total energy be on sliding halfway down the hill?

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 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.

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.

Gayle runs at a speed of 2.75 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 8.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 33.0 kg, the sled has a mass...

A 20-kg rocket sled is sliding up a 30 degree, 10-m high snow ski jumping hill from rest with constant thrust. The kinetic friction coefficient between the sled and snow is 0.2. The engine is turned off when the sled leaves the hill and it lands 50-m away from where it left the hill at ground level. The drag due to air resistance is negligible. What is the magnitude of thrust of the rocket sled? Edit: This is the question...
