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 at rest. How high does the combined bullet and baseball rise after the collision, assuming the bullet embeds itself in the ball?

A bullet of mass 5.00 g is fired horizontally into a wooden block of mass 1.16...

A bullet of mass 5.00 g is fired horizontally into a wooden block of mass 1.16 kg resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.240. The bullet remains embedded in the block, which is observed to slide a distance 0.200 m along the surface before stopping. Part A What was the initial speed of the bullet?

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.

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 bullet is firef horizontally into an initially stationary block of wood suspended by a string and remains embedded in the block. The bullets mass is m=0.0085kg while that of the block is M=0.99kg. After the collision the block/bullet system swings and reaches a maximum height of h=1.15m above inital height. Neglect air resostance. A.)Enter an expression for the speed of the block/bullet system immediately after the collision in terms of defined quantities and g. b.)enter an expression for the...

A bullet is shot horizontally and becomes embedded in a large block, which is initially at rest on a horizontal surface. How far will the block slide before stopping? The mass of the bullet is 12.6 g, the mass of the block is 9.8 kg, the bullet's impact speed is 710 m/s, and the coefficient of kinetic friction between the block and the surface is 0.220. (Assume that the block does not spin after being hit with the bullet.)

A 12.7 g bullet is fired into a block of wood at 245 m/s. The block is attached to a spring constant of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass of the wooden block.

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...
