A bullet of mass 1.8×10−3 kg embeds itself in a wooden block with mass 0.987 kg , which then compresses a spring (k = 150 N/m ) by a distance 5.5×10−2 m before coming to rest. The coefficient of kinetic friction between the block and table is 0.54.
What is the initial speed of the bullet? Vinit==?
What fraction of the bullet's initial kinetic energy is dissipated (in damage to the wooden block, rising temperature, etc.) in the collision between the bullet and the block? ΔK/K=???

A 10.0-g bullet is fired into, and embeds itself in, a 1.95-kg block attached to a spring with a force constant of 20.0 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.
