"Rocket Man" has a propulsion unit strapped to his back. He starts from rest on the ground, fires the unit, and accelerates straight upward. At a height of 14 m, his speed is 5.2 m/s. His mass, including the propulsion unit, has the approximately constant value of 135 kg. Find the work done by the force generated by the propulsion unit.
