Haloke does 176 J of work lifting himself 0.300 m at a constant speed. What is Haloke's mass?

Since he's lifting himself at constant speed ... not accelerating ... the net vertical force on him is zero, meaning that he must be lifting with force that's exactly equal to his weight.
Potential energy he added during the lift = (mass) x (gravity) x (height)
Mass = (energy) / (gravity x height) = 176 / (9.8 x 0.3) = 59.864 kg

To find Haloke's mass, we use the work formula W = m g h rearranged to m = g h W ​ . Substituting in the values, Haloke's mass is approximately 59.8 kg. This shows that the work done in lifting himself at a constant speed is equal to the gravitational potential energy gained.
