A 9.7-g lead bullet is fired into a fence post. The initial speed of the bullet is 710 m/s, and when it comes to rest, half its kinetic energy goes into heating the bullet. How much does the bullet's temperature increase? Problem 16.38 Revievw Part A A 9.7-g lead bullet is fired into a fence post. The initial speed of the bullet is 710 m/s, and when it comes to rest, half its kinetic energy goes into heating the bullet....
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
A 5.00-g lead bullet moving at 400 m/s penetrates a wood block and comes to rest inside the block. If half of its kinetic energy goes into heating the bullet, what is the bullet's change in temperature? The specific heat of lead is 128 J/ (kg*K).
A 9.7-g bullet is fired into a stationary block of wood having mass m = 5.02 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.610 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.)
Not A 5.00-g bullet moving with an initial speed of v 410 m/s is fired into and passes through a 1.00-kg block as shown in the figure below. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 940 N/m. The block moves d-5.60 cm to the right after impact before being brought to rest by the spring (a) Find the speed at which the bullet emerges from the block 146 your-esponse...

Part A The speed of a bullet can be measured by firing it at a wooden cart initially at rest and measuring the speed of the cart with the bullet embedded in it. (Figure 1) shows a 12-g bullet fired at a 5.0 -kg cart. After the collision, the cart rolls at 1.7 m/s. What is the bullet's speed before it strikes the cart?

A bullet of mass 12.5 g is fired into an initially stationary block and comes to rest in the block. The block, of mass 1.12 kg, is subject to no horizontal external forces during the collision with the bullet. After the collision, the block is observed to move at a speed of 4.70 m/s. (a) Find the initial speed of the bullet. (b) How much kinetic energy is lost?
A bullet of mass 10.2 g is fired into an initially stationary block and comes to rest in the block. The block, of mass 1.23 kg, is subject to no horizontal external forces during the collision with the bullet. After the collision, the block is observed to move at a speed of 5.80 m/s. (a) Find the initial speed of the bullet. (b) How much kinetic energy is lost?
A 5.00-9 bullet moving with an initial speed of v. = 430 m/s is fired into and passes through a 1.00-kg block as shown in the figure below. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 910 N/m. The block moves d = 6.00 cm to the right after impact before being brought to rest by the spring. M (a) Find the speed at which the bullet emerges from the...
