Your friend throws a basketball straight up in the air as hard as he can. When the ball leaves his hand, it is at 1.80 m above the ground. You run a stopwatch and find that it takes the ball 3.26 s to hit the ground (0.00 m). Assume the only acceleration on the ball is acceleration of gravity. Find the initial velocity of the basketball. (your answer must include units)
(a)
