By calculating numerical quantities for a multiparticle system, one can get a concrete sense of the meaning of the relationships p with arrowsys = Mtotv with arrowCM and Ktot = Ktrans + Krel. Consider an object consisting of two balls connected by a spring, whose stiffness is 560 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 0.39 m, and the two balls at the ends of the spring have the following masses and velocities:
• 1: 7 kg, ‹ 4, 12, 0 › m/s
• 2: 5 kg, ‹ −4, 10, 0 › m/s
(a) For this system, calculate p with arrowsys = <8,134,0> Correct
(b) Calculate v with arrowCM = <.666,11.1666,0> Correct
(c) Calculate Ktot =
(d) Calculate Ktrans =
(e) Calculate Krel =
