In a castle, overlooking a river, a cannon was once employed to fire at enemy ships. One ship was hit by a cannonball at a horizontal distance of 150 m from the cannon as shown in the figure below. The height of the cannon above the river was 67 m and the cannonball was fired horizontally. Assume the air resistance was negligible. By calculation or scale drawing, find the magnitude and direction of the velocity of the cannonball just before it hit the ship.
