A(n) 0.488 kg soccer ball approaches a player horizontally with a speed of 11.1 m/s. the player illegally strikes the ball with her hand and causes it to move in the opposite direction with a speed of 30.3 m/s. what is the magnitude of the impulse delivered to the ball by the player? answer in units of kg m/s. provide an explanation of the equation you ty!

Abasketball star covers 2.65 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 0.910 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. (c) determine his vertical velocity at the instant of takeoff. (d) determine 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 = 2.45 m, and yf = 0.750 m.
