A man throws a rock of mass m = 0.310 kg straight up into the air. In this process, his arm does a total amount of work Wnet = 105 J on the rock. Calculate the maximum distance, h, above the man's throwing hand that the rock will travel. Neglect air resistance.

Wnet = m g H
Solve for the maximum height reached, H.
Is Wnet 105 or 10^5 joules? 105 is more likely

Yes, Wnet is 105 J.
