A 9 g lead bullet leaves the rifle at a temperature of 110°C and hits a steel plate. If the bullet melts on impact, what is the minimum speed it must have?
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
A 50.0-gram lead bullet hits a steel plate, both initially at 25 °C. The bullet melts and splatters on impact. Assuming that the bullet receives 88% 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)
A 90.0-gram lead bullet hits a steel plate, both initially at 29 °C. The bullet melts and splatters on impact. Assuming that the bullet receives 76% 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)
. A rifle that weights 1.5 kg fires a 6 g bullet. The bullet leaves the rifle traveling at 700 m/s. What is the recoil speed of the rifle?
A 4.0-g bullet leaves the muzzle of a rifle with a speed of 328 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.75-m-long barrel of the rifle? A 4.0-g bullet leaves the muzzle of a rifle with a speed of 328 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.75-m-long barrel of the rifle? 765 Your response differs from the correct answer by more...
A 12g bullet is fired from a 3.09 kg rifle. After the bullet leaves the rifle it moves at a speed of 308 m/s. What is the magnitude of the impulse imparted on the rifle?
If a bullet leaves the muzzle of a rifle with a speed of 600m/s, and the barrel ofthe rifle is 0.9m long, what is the acceleration of the bullet while in the barrel?
a) A bullet is fired from a rifle pointed 45 degrees above horizontal. The bullet leaves the muzzle traveling 1400 m/s. How many seconds does it take the bullet to reach the high point of its trajectory? b) What is the bullet's height at the highest point? Express the answer in km. c) How far away from where the gun is fired does the bullet land? Answer in km.
When a bullet leaves a rifle it has a lot of kinetic energy, most of which gets lost as heat. Imagine that a 9.8kg lead bullet is fired into a ort upon which the actual target was sitting . The bullets initial speed is 760 m/s, and as it comes to rest half of its kinetic energy goes into heating the bullet. How much does the bullets temperature increase
