A basketball leaves a player's hands at a height of 2.00m  above the floor. The basket is 3.05 m above the floor. The player likes to shoot the ball at a 40.0度 angle

Part A

If the shot is made from a horizontal distance of 10.00 m and must be accurate to(+-0.22m  (horizontally)), what is the range of initial speed allowed to make the basket?

求出初速的最大和最小?       單位 秒 公尺

最大和最小怎麼分啊?
