To solve for the velocity of the ball as it was launched, we can use the formula for kinetic energy:

Kinetic energy = (1/2) * mass * velocity^2

Given kinetic energy = 25 J and mass = 2 kg, we can rearrange the formula to solve for velocity:

25 J = (1/2) * 2 kg * velocity^2

Simplifying the equation:

50 J = 2 kg * velocity^2

Dividing both sides by 2 kg:

25 = velocity^2

Taking the square root of both sides:

velocity = √25

velocity = 5 m/s

Therefore, the velocity of the ball as it was launched is 5 m/s.
