A child and sled with a combined mass of 52.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 3.70 m/s at the bottom, what is the height of the hill? A child and sled with a combined mass of 2.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 3.70 m/s at the bottom, what is the height of the hill? m
Gayle runs at a speed of 3.45 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 5.00 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 52.0 kg, the sled has a mass...
Gayle runs at a speed of 4.30 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 5.00 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 47.5 kg, the sled has a mass...
Starting from rest, a 29.2 kg child rides frictionless ski slope. At the bottom of the hill, her speed is 8.25 kg sled down a a 6.8 m/s. If the slope makes an angle of 15.5° with respect to the horizontal, how far along the hill did she slide on C her sled? 0.235 distance Momentum and Energy 2 Based on the previous question you can conclude that if two objects of different mass have the same magnitude of momentum,...
Starting from rest, a 30.6 kg child rides a 7.75 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 6.0 m/s . If the slope makes an angle of 13.3° with respect to the horizontal, how far along the hill did she slide on her sled? Child on a sled sliding down a slope from right to left. distance= __________
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.
A child and sled with a combined mass of 49.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 2.40 m/s at the bottom, what is the height of the hill? m
A child and sled with a combined mass of 59.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 2.00 m/s at the bottom, what is the height of the hill?
1. )A child and sled with a combined mass of 50.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 2.50 m/s at the bottom, what is the height of the hill? ____ m
Starting from rest, a 28.6 kg child rides a 8.75 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 7.2 m/s . If the slope makes an angle of 14.5° with respect to the horizontal, how far along the hill did she slide on her sled?
