5.( A vs Assume that Professor Selsby is moving towards a bridge with constant speed, 8.5 m/s as shown. A student, on the bridge, wants to drop a water balloon, O, so that it hits the professor directly on the head. The balloon is exactly 18.3 meters above the professors' head when the student releases the balloon from rest. What horizontal distance from the bridge, D, should the professors head be when the student releases the ball? 18.3m →vs = 8.5m/s -0← balloon dropped from rest -> Find this distance D
