if you can solve all questions. . thank you.

A basketball star covers 3.10 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 of mass. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.90 m above the floor and is at elevation 0.850 m when he touches down again. (a) Determine his time of flight (his "hang time"). (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 (e) For comparison, determine the hang time of a whitetail deer making a jump with center-of- mass elevations y, = 1.20 m, Ymax = 2.45 m, and y = 0.740 m
