Final answer:
To calculate the work done by the force of the waterboy on the cooler, multiply the mass of the cooler by the height of the stairs and the acceleration due to gravity.
Step-by-step explanation:
To calculate the work done by the force of the waterboy on the cooler, we need to use the formula for work: W = F * d * cos(theta). In this case, the force of the waterboy is equal to the weight of the cooler, which is given by mg, where m is the mass of the cooler and g is the acceleration due to gravity. The distance, d, is the height of the stairs. So the work done is given by W = mgd.
