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 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 20.0 g bullet moving at 1,000 m/s is fired through a one kg block of wood emerging at a speedof 100 m/s. If the block had been originally at rest and is free tomove, 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?
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.
A 10.2 g bullet is fired into a stationary block of wood (M= 4.60 kg). The relative motion of the bullet stops inside the block. The speed of the bullet plus wood combination is measured at 0.700 m/s. What was the original speed of the bullet?
A 9.60 g bullet is fired into a stationary block of wood (M= 4.40 kg). The relative motion of the bullet stops inside the block. The speed of the bullet plus wood combination is measured at 0.750 m/s. What was the original speed of the bullet? 301 m/s 5.08 m/s 316 m/s 345 m/s 313 m/s
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...
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...
