A boy throws a ball at 5.5 m/s at an angle of 25.4° above the horizontal off a cliff which is 70.8 m high. What angle does the velocity of the ball make with the horizontal 0.78 s after the throw? (make the angle positive if the angle is above the horizontal, and negative if it is below the horizontal)
