You are shooting a basketball into a hoop of diameter d that is located l meters away and h meters high. Assume that the horizontal distance to the hoop is measured with its center and you and your basketball can be treated as a point. If you can always shoot the ball with the same initial launch angle 0, what is the range of the initial shoot velocity v in order to score? As always, start your argument from the basic equations of motion.
