Abody is traveling at 5.0 m/s along the positive direction of an x axis; no net force acts on the body. an internal explosion separates the body into two parts, each of mass 4 kg, and increases the total kinetic energy by 100 j. the forward part continues to move in the original direction of motion. (a) what is the speed of the rear part? (b) what is the speed of the forward part?

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
