A basketball player grabbing a rebound jumps 76.1 cm vertically. How much total time (ascent and descent) does the player spend (a) in the top 14.4 cm of this jump and (b) in the bottom 14.4 cm? Do your results explain why such players seem to hang in the air at the top of a jump? so the only thing i thought of doing was finding the initial velocity Vi^2 = -2ax Vi= 3.86 m/s now i have no idea what do to. any help?
