How much is the spring compressed?A 3 kg block is fastened to a vertical string that has a spring constant of 800 N/m. A 1.2 kg block rests on top of the 3 kg block. When the blocks are at rest, how much is the spring compressed from its uncompressed length?Block A has a mass mA and is attached to a spring having a stiffness k and an unstretched length l0. If another block B, having a mass mB, is pressed against A so that the spring deforms a distance d, determine the distance both blocks slide on the smooth surface before they begin to separate. What is their velocity at this instance?

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.) mA 12.0-g bullet is fired horizontally into a 109-g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 144 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 87.0 cm, what was the speed of the bullet at impact with the block? m/s
