A machine used for tennis training fires a tennis ball at varying speeds and angles to the horizontal. Two such machines are placed side-by-side both set to fire balls horizontally. One machine is set such the initial speed of the ball means that the ball travels 30m before hitting the ground. The second machine is set at a lower speed so that the ball only travels 10m. Neglecting air resistance, which of the following is true if both machines are fired at the same instant?
