Farhan tosses a ball upwards with an initial velocity of 13.0 m/s. What is the direction of motion of the ball 2.4 seconds after he threw it? type "up" if it is moving up and "down" if it is moving down
The vertical velocity component decreases by g t = 23.5 m/s in 2.4 seconds. That will make it a negative number, changing its direction.
Now what do you think the answer is? You do the typing.
