A ball was dropped from a bridge that is 105 m above
a river. At the same time, a toy water rocket is fired
into the air from a barge that is 1.50 m high, at an
initial velocity of 26.2 m/s. How long after the ball was
dropped will the toy rocket and the ball be at the same
height above the water?* IT
