1. A 23-g bullet traveling 230 m/sm/s penetrates a 4.9 kg block of wood and emerges cleanly at 175 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges? 2. A 11800 kg railroad car travels alone on a level frictionless track with a constant speed of 24.5 m/s. A 6800 kg load, initially at rest, is dropped onto the car. What will be the car's new speed?
A 24 g lead bullet traveling at 360 m/s penetrates a 1.4 kg lead block and stops. By how much does the temperature of the block and bullet increase If all the kinetic energy of the bullet is absorbed. (Use cPb= 128 J*K/kg) DT= Kelvin
A 7.00 g bullet, when fired from a gun into a 0.80 kg block of wood held in a vise, penetrates the block to a depth of 7.00 cm. This block of wood is next placed on a frictionless horizontal surface, and a second 7.00 g bullet is fired from the gun into the block. To what depth will the bullet penetrate the block in this case? (............) cm
A 4.25-g bullet traveling horizontally with a velocity of magnitude 375 m/s is fired into a wooden block with mass 1.10 kg, initially at rest on a level frictionless surface. The bullet passes through the block and emerges with its speed reduced to 126 m/s. Part A How fast is the block moving just after the bullet emerges from it? Express your answer in meters per second.

A 0.0101-kg bullet traveling horizontally at 412 m/s strikes a 3.84-kg block of wood sitting at the edge of a table. The bullet is lodged into the wood. If the table height is 1.08 m, how far from the table does the block hit the floor?
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 0.11 kg bullet traveling at speed hits a 18.3 kg block of wood and stays in the wood. The block with the bullet imbedded in it moves forward with a velocity of 8.8 m/s. What was the velocity (speed) of the bullet immediately before it hit the block (in m/s)?
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 0.014 kg bullet traveling horizontally at 403 m/s strikes a 4 kg block of wood sitting at the very edge of a horizontal table of height 1 meters. The bullet is lodged into the wood. [For the signs of directions in this problem, take forward and upward to be positive; backward and down to be negative.] a) What is the momentum of the bullet right before it impacts the block of wood? b) What is the momentum of the...
In a ballistics test, a 25 g bullet traveling horizontally at 1200 m/s goes through a 45 cm thick 350 kg stationary target and emerges with a speed of 1000 m/s. The target is free to slide on a smooth horizontal surface. (a) How long is the bullet in the target (assume constant acceleration)? s What average force does it exert on the target? N (magnitude only) (b) What is the target's speed just after the bullet emerges?
