Answer:
The acceleration of the ball is
Explanation:
From the question we are told that
The maximum height the ball reachs is
The horizontal component of the initial velocity of the ball is
The vertical component of the initial velocity of the ball is
The vertically motion of the ball can be mathematically represented as
Here the final velocity at the maximum height is zero so
Making the acceleration the subject we have
substituting values
The negative sign shows that the direction of the acceleration is in the negative y-axis
