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 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 20-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. If the block had been originally at rest and is free to move, what is its resulting speed?
A 2.9 kg block of wood sits on a frictionless table. A 3.0 g bullet, fired horizontally at a speed of 480 m/s goes completely through the block emerging at a speed of 250 m/s. What is the speed of the block of wood immediately after the bullet exits?
A 3.8 kg block of wood sits on a table. A 3.0 g bullet, fired horizontally at a speed of 460 m/s, goes completely through the block, emerging at a speed of 250 m/s. What is the speed of the block immediately after the bullet exits?
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?
A 2.8 kg block of wood sits on a table. A 3.0 g bullet, fired horizontally at a speed of 550 m/s , goes completely through the block, emerging at a speed of 220 m/s . What is the speed of the block immediately after the bullet exits? Express your answer to two significant figures and include the appropriate units.
QUESTION 5 10 points If a bullet moving with a speed of 200 m/s has a momentum of magnitude 4.00 kg.m/s, what would the magnitude of its momentum be if it was moving with a speed of 321 m/s, in units of kg.m/s? 10 points QUESTION 6 A ball of mass 1.09 kg is moving with a speed of 14.9 m/s. What is the magnitude of the momentum of the ball, in units of kg.m/s? 10 points QUESTION 7 A...
A 9.5-g bullet is fired into a stationary block of wood having mass m = 4.99 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.606 m/s. What was the original speed of the bullet?
A 9.5-g bullet is fired into a stationary block of wood having mass m = 5.04 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.593 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.) m/s
A 10.4-g bullet is fired into a stationary block of wood having mass m = 4.99 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.592 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.)
