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

Which of the following statements are true about the energy of the two bullet-block systems immediately after the collisions? (Select all that apply.) (d) The two bullet-block systems have the same total energy. More energy from the bullet went into deforming the block in the first case (bullet in center) than the second (bullet closer to its edge). The same amount of energy went into deforming the block in both cases. The two bullet-block systems have the same translational kinetic...

A 3.90 g bullet moving at 300 m/s enters and stops in an initially stationary 2.80 kg wooden block on a horizontal frictionless surface. What's the speed of the bullet/ block combination? What fraction of the bullet's kinetic energy was lost in this perfectly inelastic collision? How much work was done in stopping the bullet? If the bullet penetrated 5.00 cm into the wood, what was the average stopping force?
