A rifle bullet with mass 15.0 g strikes and embeds itself in a block of mass 1.500 kg that rests on a frictionless, horizontal surface and is attached to a coil spring. The spring was relaxed at the beginning. The spring constant is 550 N/m. The initial velocity of the bullet was 700 m/s. The impact compresses the spring by x (see figure below). 1) Find the magnitude of the block's velocity (with the bullet stuck inside) after the impact...

A 10.0-g bullet is fired into, and embeds itself in, a 1.85-kg block attached to a spring with a force constant of 22.4 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. (No Response)...

5. A bullet with a mass 0.850 g is fired in to a hanging block which is free to swing (recall ballistic pendulum). Mass of the hanging block is 6.4 kg. The bullet comes to rest as it is fired to the block and the block + bullet then swing upward vertically displacing the center of mass of the system by 7. 2 cm before the system comes momentarily to rest at the end of the arc. What is the...

A bullet is fired toward a block of wood (m1 = 1.17 kg) sitting on a frictionless surface. The bullet has a mass mb = 30 g, and its initial velocity is 320 m/s in the +x-direction. The bullet embeds itself inside the block of wood. Then the block of wood (with bullet) collides with another block of wood (m2 = 1.20 kg). The collision is elastic. The first block moves off at an angle of -45o with respect to...

Block of mass 10 kg is hit and penetrated by a 50 g bullet. As result of the collision the “block + bullet system.” (Originally on the horizontal frictionless table) enters the horizontal rough surface ( μkin=0.7) and stops after 5m. Find the entropy change due to the inelastic collision (∆Scollision) and the entropy change due to friction (∆Sfrict),. The temperature remains constant throughout these processes (T=27C)

A bullet of mass m = 2.40×10-2 kg is fired along an incline and embeds itself quickly into a block of wood of mass M = 1.35 kg. The block and bullet then slide up the incline, assumed frictionless, and rise to a height H = 1.35 m before stopping. Calculate the speed of the bullet just before it hits the wood.

The bullet remains embedded in the block slides along the surface before stopping. What distance does the block slide before coming to rest?
