Answer:

Explanation:

velocity of projection = vo

angle of projection = θ

When the ball is at maximum height, its vertical component of velocity is zero, So it has only the horizontal component of velocity at highest point.

velocity at highest point = vo Cos θ

The acceleration acting on the ball is only the acceleration due to gravity which always acts vertically downward.

So, teh acceleration of the ball at the highest point is g.
