You throw a basketball from a cliff to the ground. The ball has an initial velocity of 12 m/s in the horizontal direction. After 3.0 seconds, the ball has a velocity of -30.0 m/s in the y-direction. What is the direction of motion of the ball at time t= 3.0 s? (Hint: direction is related to the angle).

), in sexagesimal degrees, is calculated by this trigonometrical expression:
(1)
- Horizontal velocity, in meters per second.
- Vertical velocity, in meters per second. 
and 
, then the direction of motion of the ball is:
