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
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
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 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 sled and rider with a combined weight of 46 kg are at rest on the top of a hill 29 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 90.0-gram lead bullet hits a steel plate, both initially at 24 °C. The bullet melts and splatters on impact. Assuming that the bullet receives 74% of its kinetic energy as heat energy, at what minimum speed must it be traveling to melt on impact? (The melting temperature of Lead is 327°C) _____ m/s
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?
1) Shayla is sliding in a sled from a top of a 5-m-high snow hill ( starting from rest.) At the bottom of the hill, her sled hits Tom, who falls into the sled. Toms's mass is the same as Shayla's and her sled altogether. What is the speed of the sled after Tom fell in? Neglect friction w/ snow. 2) You are standing by a smooth frozen lake, and longing to propel a snowball over the lake. In which...
A sled with rider having a combined mass of 120 kg travels with initial speed 24 m/s up a perfectly smooth icy hill. At the top of the 8.2 m high hill is a cliff that drops straight down. After the sled travels over the edge of the cliff, how far from the foot of the cliff does the sled land? _________m (It's a 'work' related problem)
