question

All walking animals, including humans, have a natural walking pace—a number of steps per minute that is more comfortable than a faster or slower pace. Suppose that this pace corresponds to the oscillation of the leg as a physical pendulum.  Fossil evidence shows that T. rex, a two-legged dinosaur that lived about 65 million years ago, had a leg length L = 3.1 m and a stride length S = 4.0 m (the distance from one footprint to the next print of the same foot).  Estimate the walking speed of T. rex. (Unit: m/s)
