A bullet of mass 0.017 kg traveling horizontally at a high speed of 210 m/s embeds itself in a block of mass 5 kg that is sitting at rest on a nearly frictionless surface. (a) What is the speed of the block after the bullet embeds itself in the block? Vr = 42 x m/s (b) Calculate the total translational kinetic energy before and after the collision. Ktrans,i = 374.85 Ktrans,f= (c) Compare the two results and explain why there...

A bullet of mass 20 kg is moving at 400 m/s and strikes a 1.5 kg block. The bullet embeds itself in the block, which starts sliding across the table it was sitting on. How fast is the block moving after the collision?
A bullet of mass 0.056 kg traveling horizontally at a speed of 100 m/s embeds itself in a block of mass 1.5 kg that is sitting at rest on a nearly frictionless surface. (a) What is the speed of the block after the bullet embeds itself in the block? v= m/s (b) Calculate the kinetic energy of the bullet plus the block before the collision: K; = (c) Calculate the kinetic energy of the bullet plus the block after the...
A 10.0 gram bullet traveling at 275 m/s strikes and embeds itself in a 3.490 kg block of wood held on a frictionless table by a spring having k= 50.0 kg/sec^2. Calculate the speed of the block immediately after the collision and the compression of the spring in meters.
A bullet of unknown mass, mb , is shot at and explodes through a can of mass mc = 2 kg that is sitting on top of a frictionless table. The bullet was travelling at vi = 100 m/s before it strikes the can and afterwards the bullet has slowed to vf = 30 m/s. After the collision, the can slides to the edge of the table with a speed of vtop = 3.2 m/s and falls to the ground....
A bullet with mass m = 40 grams traveling at v = 400 m/s strikes a block of wood suspended from a ceiling with a massless cord. The collision last for 15 milliseconds, and after it is completed the bullet embeds itself into the block. Then, the combined system rises to a maximum height has its swings upward as shown. The mass of the wooden block is M=5.0kg and the length of the cord is L = 1.25 m. Calculate...
a bullet of mass m1 =5g is moving with speed v1. it strikes a block of mass m2=6 kg that is hanging at rest from a cord. the bullet embeds itself into the block and the bullet and block swing up on the cord , coming to rest at a height h=2 cm above the original position of the block. whatbisnthe correct expression for momentum conservation when the bullet strikes the block?
A 10.0-g bullet is fired into, and embeds itself in, a 1.95-kg block attached to a spring with a force constant of 20.0 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and the block slides on a frictionless surface? Note: You must use conservation of momentum in this problem because of the inelastic collision between the bullet and block.
A 10.0-g bullet is fired into, and embeds itself in, a 1.80-kg block attached to a spring with a force constant of 22.3 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and the block slides on a frictionless surface? Note: You must use conservation of momentum in this problem because of the inelastic collision between the bullet and block.
