Answer:
Zero
Explanation:
The motion of the ball is the motion of a projectile, and it consists of two independent motions:
- A horizontal motion with constant velocity
- A vertical motion with constant acceleration g =9.8 m/s^2 towards the ground
We are only interested in the vertical component of the velocity, which is given by
where
v0 = 32 m/s is the initial speed
is the initial direction
t is the time
The vertical component of the velocity decreases until the ball reaches its maximum height. At that moment, the vertical velocity becomes zero, and then it changes direction (pointing downward).
