First of all, let's multiply by t on both sides:

And then, let's divide by v on both sides:

So, finally

Answer:
-2.5 is the answer to your question
We are given the gravitational potential energy and the height of the ball and is asked in the problem to determine the mass of the ball. the formula to be followed is PE = mgh where g is the gravitational acceleration equal to 9.81 m/s^2. substituting, 58.8 J = m*9.8 m/s^2 * 30 m; m = 0.2 kg.
