Question:

A basketball star covers 2.80 m horizontally in a jump to dunk the ball (Fig. P4.24). His motion through space can be modeled precisely as that of a particle at his center of mass, which we will define in Chapter 9. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.85 m above the floor, and is at elevation 0.900 m when he touches down again. Determine
(a) His time of Flight (his €œhang time€),
(b) His horizontal and
(c) Vertical velocity components at the instant of takeoff, and
(d) His takeoff angle.
(e) For comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.50 m, yf = 0.700 m.
