#### Answer:

The height is

#### Explanation:

The energy stored in the spring will be converted to kinetic energy and this will give the initial speed of the ball.

Mass is

Spring constant is

Compression is

Energy in the spring

Kinetic energy is

We apply the equation of motion

To find the greatest height

So,
