A 22.3-g bullet moving at 1 000 m/s is fired through a one-kg block of wood emerging at a speed of 100 m/s. What is the change in the kinetic energy of the bullet-block system as a result of the collision assuming the block is free to move?

A 12g bullet is fired into a 12kg wood block that is at rest on a wood table. The block, with the bullet embedded, slides 5.0cm across the table. The coefficient of kinetic friction for wood sliding on wood is 0.20. awnser should be in m/s
A 26.0-g bullet moving at 1 200 m/s is fired through a one-kg block of wood...
A 26.0-g bullet moving at 1 200 m/s is fired through a one-kg block of wood emerging at a speed of 200 m/s. What is the kinetic energy of the block that results from the collision if the block had not been moving prior to the collision and was free to move?

A bullet of mass m is fired into a block of mass M that is at rest. The block, with the bullet embedded, slides distance d across a horizontal surface. The coefficient of kinetic friction is ?k. Part A Find an expression for the bullet's speed vbullet. Part B What is the speed of a 9.0 g bullet that, when fired into a 12 kg stationary wood block, causes the block to slide 5.4 cm across a wood table? Assume...
A bullet of mass m is fired horizontally into a block of wood of mass M...
A bullet of mass m is fired horizontally into a block of wood of mass M lying on a table. The bullet remains in the block and they slide a distance d after the collision. The coefficient of kinetic friction between the wooden block and the table is u. What was the speed of the bullet before the collsion? let m=.020 kg, M=2.00 kg, u=.500, and d=3.00m
7.HW. A bullet is fired into a block of wood sitting on a block of ice....
7.HW. A bullet is fired into a block of wood sitting on a block of ice. The bullet has an initial velocity of 500m/s and a mass of 0.005kg. The wooden block has a mass of 1.2kg and is initially at rest. The bullet remains embedded in the wood afterward. (so hit and stick situation) A)Assuming that momentum is conserved, find the velocity of the block of wood and bullet after the Collision. (so momentum before = momentum. V1’=V2'=V') B)What...
A bullet with a mass of 4.1 g and a speed of 650 m/s is fired...
A bullet with a mass of 4.1 g and a speed of 650 m/s is fired at a block of wood with a mass of 9.6x10-2 kg. The block rests on a frictionless surface and is thin enough that the bullet passes completely through it. Immediately after the bullet exits the block, the speed of the block is 21 m/s. a. What is the speed of the bullet when it exits the block? b. Is the final kinetic energy of...

Please fast
A 10.0 g bullet is fired into a stationary block of wood (m = 5.00 kg). The relative motion o t e bullet stops inside the block. The speed of the bullet-plus-block combination immediately after the collision is 0.600 m/s. What was the speed of the bullet before the collision? How much energy was lost in the collision?

12. (20 points) A 5 gram bullet is fired at a wood block that is supported at rest on a smooth incline plane (no friction) at an angle of theta above the horizontal. The bullet is fired with a speed of 500 m/s, but then impacts and passes straight through the wood block, coming out the other side with a speed of 400 m/s. As a result of the collision, the wood block slides up the ramp 5 cm from...
