A basketball star covers 3.00 m horizontally in a jump to dunk the ball. His motion through space can be modeled precisely as that of a particle at his center ofmass. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.95 m above the floor and is at elevation 0.860 m when he touches down again. (a) Determine his time of flight (his "hang time"). s (b) Determine his horizontal velocity at the instant of takeoff. m/s (c) Determine his vertical velocity at the instant of takeoff. m/s (d) Determine his takeoff angle. above the horizontal
