A basketball star covers 2.80 m horizontally in a jump to dunk theball. His motion through space can be modeled precisely as that ofa particle at his center of mass, His center of mass is atelevation 1.02 m when he leaves the floor. It reaches a
maximum height of 1.85 m above the floor, and is at elevation 0.900m when he touches down again.
Determine
(a) his time of flight (his âhang timeâ),
(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 deermaking a jump with center-of-mass elevations yi = 1.20 m, ymax =2.50 m, yf = 0.700 m.
