    A forensic scientist calibrating a spring finds that if a force of 0.750 N is applied the spring, it will compress a distance of 0.250 cm. The same spring is then used in a ballistics experiment: a rifle bullet of mass 8.00 g collides with and embeds itself in a block of mass 0.992 kg that was initially at rest on a horizontal frictionless surface. The block is attached to the spring as shown. The impact compresses the spring 15.0...
