2–62 An exercise room has 6 weight-lifting machines that have no motors and 7 treadmills each equipped with a 2.5-hp (shaft output) motor. The motors operate at an average load factor of 0.7, at which their efficiency is 0.77. During peak evening hours, all 13 pieces of exercising equipment are used continuously, and there are also two people doing light exercises while waiting in line for one piece of the equipment. Assuming the average rate of heat dissipation from people in an exercise room is 600 W, determine the rate of heat gain of the exercise room from people and the equipment at peak load conditions. 2–63 A room is cooled by circulating chilled water through a heat exchanger located in a room. The air is circulated through the heat exchanger by a 0.25-hp (shaft output) fan. Typical efficiency of small electric motors driving 0.25-hp equipment is 54 percent. Determine the rate of heat supply by the fan-motor assembly to the room.

A. (3 pts) g v(t) An object of mass m is released from rest at a height h above the ground and experiences air resistance as it falls. The object increases its speed v until it reaches a terminal speed $v_{term}$ before it hits the ground. The magnitude of the air resistance force acting on the object just before it reaches terminal speed is given by $F_{drag} = bv^2$ where b is a positive constant. The downward acceleration of gravity is g. What is the terminal speed $v_{term}$? Express your answer in terms of m, b, h, and g as needed.
