Question

An elephant's legs have a reasonably uniform cross section from top to bottom, and they are quite long, pivoting high on the animal's body. When an elephant moves at a walk, it uses very little energy to bring its legs forward, simply allowing them to swing like pendulums. For fluid walking motion, this time should be half the time for a complete stride; as soon as the right leg finishes swinging forward, the elephant plants the right foot and begins swinging the left leg forward.

Part A

An elephant has legs that stretch 2.3 m from its shoulders to the ground. How much time is required for one leg to swing forward after completing a stride?

Express your answer to two significant figures and include the appropriate units.

t= ??? seconds

Part B

What would you predict for this elephant's stride frequency? That is, how many steps per minute will the elephant take?

Express your answer as an integer.

Answer= ??? steps/minute

Explanation / Answer

It's actually 1.2 s and 97 steps/minute
