Question

A pronghorn antelope can run at a remarkable 18 m/s for up to 10 minutes, almost triple the speed that an elite human runner can maintain. For a 32 kg pronghorn, this requires an astonishing 3.4 kW of metabolic power, which leads to a significant increase in body temperature.

If the pronghorn had no way to exhaust heat to the environment, by how much would its body temperature increase during this run? (In fact, it will lose some heat, so the rise won't be this dramatic, but it will be quite noticeable, requiring adaptations that keep the pronghorn's brain cooler than its body in such circumstances.) Assume the efficiency of the pronghorn to be equal to that of human.
