A 0.004 kg bullet is fired into a 0.200 kg wooden block at rest on a horizontal surface. After impact, the embedded bullet block slides 8.00 m before coming to rest. If the coefficient of friction is 0.400, what is the speed of the bullet before impact?
 a) 96 m /s
 b) 112 m/s 
c) 286 m/s 
d) 404 m/s 
e) 812 m/s

A 0.0147-kg bullet is fired straight up at a falling wooden block that has a mass of 2.94 kg. The bullet has a speed of 760 m/s when it strikes the block. The block originally was dropped from rest from the top of a building and had been falling for a time t when the collision with the bullet occurs. As a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to a...

A 0.00618-kg bullet is fired straight up at a falling wooden block that has a mass of 1.52 kg. The bullet has a speed of 616 m/s when it strikes the block. The block originally was dropped from rest from the top of a building and had been falling for a time t when the collision with the bullet occurs. As a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to a...

A bullet of mass m = 29 g is fired into a wooden block of mass...

A bullet of mass m = 29 g is fired into a wooden block of mass M = 4.9 kg as shown in the figure below. The block is attached to a string of length 1.5 m. The bullet is embedded in the block, causing the block to then swing as shown in the figure. If the block reaches a maximum height of h = 0.27 m, what was the initial speed of the bullet?

A) A 12.0-g bullet is fired horizontally into a 113-g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 149 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 76.0 cm, what was the speed of the bullet at impact with the block? B)A 0.033-kg bullet is fired vertically at 238 m/s into a 0.15-kg baseball that is initially...

A bullet of mass m1 is fired horizontally into a wooden block of mass m2 resting...

A bullet of mass m1 is fired horizontally into a wooden block of mass m2 resting on a horizontal surface. The coefficient of kinetic friction between block and surface is μk. The bullet remains embedded in the block, which is observed to slide a distance s along the surface before stopping. What was the initial speed of the bullet? Take the free-fall acceleration to be g.
