A box of 0.5 Kg is sliding with a speed of 6m/s on a frictionless, level surface toward the spring of force constant k. This hits the spring and compresses it.
a) Whenever the spring is compressed 0.1m, the speed of box is 2m/s. Determine the force constant k?
b) Determine how far will the spring be compressed when the speed of box drops to 0?
