Question

. C. VB= e. VB= Two NBA players, Alonzo and Bernard, are revered for their ability to dunk a basketball. Alonzo is a tall, heavy center: Alonzo's mass is 1.5 times Bernard's mass • Bernard is an average-height, slim guard: Bernard's vertical leap is 2.5 times Alonzo's. 1. If Alonzo's and Bernard's take-off velocities are va and VB, respectively, then: a. VB = va/2.5 b. VB = V2 = va/V2.5 va/(2.5)2 d. VB= = (va)(2.5) - VAV2.5 f. vb = = (VA)(2.5)2 2. When Alonzo and Bernard take off, they impart on the ground impulses of magnitude Ja and JB, respectively. One can conclude that: JB = (32) (JA)(2.5) b. JB = (32) (JA) (V2.5) c. JB = (32) (JA)(2.5)2 d. JB = (23) (JA)(2.5) e. (23) (A) (V2.5) f. (23) (JA)(2.5)2 a.
