Chapter 15 465 P15.66 (a) For each segment of the spring dK dm v x = 1 2 2 af . Also, v x v x = A and dm m dx = A . FIG. P15.66 Therefore, the total kinetic energy of the block-spring system is KM v xv m dx M m v =+ F H G I K J F H G I K J z 1 2 1 2 1 23 2 22 2 0 2 A A A . (b) ω = k m eff and 1 2 1 mv M m v eff F H G I K J Therefore, T M k m == + 2 2 3 π .
