Question

Calculus question!
In a natural history museum you see leg bones for two species of dinosaurs and want to know how fast they walked. The maximum walking speed S (in feet per second) of an animal can be modeled by the equation
S =square root(32L)
where L is the length (in feet) of the animal's leg. By computing the appropriate limit, find the rate of change of maximum walking speed when L = 5. Include units in your answer.
