A spring with a spring constant of 303 N/m is initially compressed by a distance of 0.056 m from its equilibrium position.

Assuming that the spring then pushes the mass across the surface, with speed does the mass leave the spring? Assume proper SI Units.

Consider two cars that can roll on a frictionless track. Initially, both cars are at rest. One car is launched from rest with a spring, and the cars undergo a completely inelastic collision. The spring constant is 850 N/m, and the spring is initially compressed by 0.075 m. The first car has a mass of 0.50 kg and the second has a mass of 1.0 kg.

A 1.00 × 10−2-kg bullet is fired horizontally into a 2.50-kg wooden block attached to one end of a massless horizontal spring (k = 845 N/m). The other end of the spring is fixed in place, and the spring is unstrained initially. The block rests on a horizontal, frictionless surface. The bullet strikes the block perpendicularly and quickly comes to a halt within it. As a result of this completely inelastic collision, the spring is compressed along its axis and causes the block/bullet to oscillate with an amplitude of 0.200 m. What is the speed of the bullet?
