Physics

To solve the problem, we can analyze the motion of the ball using the given information.

Determine the vertical velocity just before hitting the ground:

When the ball hits the ground at a angle, the horizontal and vertical components of the velocity are equal. Since the horizontal speed is :

Calculate the time of flight:

Using the vertical motion equation:

Rearranging gives:

Calculate the height of the release point:

Using the equation for vertical motion:
