A thin block of soft wood with a mass of 0.070 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 629 m/s at a block of wood and passes completely through it. The speed of the block is 25 m/s immediately after the bullet exits the block. (a) Determine the speed of the bullet as it exits the block. (b) Determine the loss of kinetic energy of...
A bullet with a mass of 4.1 g and a speed of 650 m/s is fired at a block of wood with a mass of 9.6x10-2 kg. The block rests on a frictionless surface and is thin enough that the bullet passes completely through it. Immediately after the bullet exits the block, the speed of the block is 21 m/s. a. What is the speed of the bullet when it exits the block? b. Is the final kinetic energy of...

A 5.00-9 bullet moving with an initial speed of v. = 430 m/s is fired into and passes through a 1.00-kg block as shown in the figure below. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 910 N/m. The block moves d = 6.00 cm to the right after impact before being brought to rest by the spring. M (a) Find the speed at which the bullet emerges from the...

PROBLEM 2 (5 points). Momentum and Mechanical Energy conservation A rifle bullet with mass 150 g strikes and embeds itself in a block with mass 1000 g that rests on a frictionless, horizontal surface and is attached to a coil spring. The initial velocity of the bullet was 700 m/s. The impact compresses the springy a distance x. The spring constant is 550 N/m. The spring is ideal. a) Find the magnitude of the block's velocity (with the bullet stuck...
