A basketball player is standing on the floor 10.0 m from the basket as in the figure below. The height of the basket is H = 3.05 m, and he shoots the ball at an angle, ? = 36.4°, with the horizontal from a height of h = 1.82 m.
(a) What is the acceleration of the basketball at the highest point in its trajectory? magnitude direction
(b) At what speed must the player throw the basketball so that the ball goes through the hoop without striking the backboard? m/s
