By calculating numerical quantities for a multiparticle system, one can get a concrete sense of the meaning of the relationships p→sys=Mtotv→CM and Ktot=Ktrans+Krel. Consider an object consisting of two balls connected by a spring, whose stiffness is 460 N/m. The object has been thrown through the air and is rotating and vibrating as it moves. At a particular instant the spring is stretched 0.42 m, and the two balls at the ends of the spring have the following masses and velocities: 1: 7 kg, ‹ 5, 12, 0 › m/s 2: 3 kg, ‹ 7, 9, 0 › m/s What is the total kinetic energy?
