Steven and Danny are standing apart from each other throwing a ball. Steven throws the ball to Danny and Danny throws it back immediately. Steven throws the ball with a velocity of 5.00 m/s and after 2.9 s he got the ball back. Suppose there's no deceleration of the ball when it's moving and that we can neglect the time for Danny to throw the ball. The speed of the ball when it is thrown back to Steven was 3.30 m/s. How far are they apart from each other?
