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
