Question

Suppose that during each step, the leg of a student swings through a total distance of 2.0 m. At the end of the swing, this foot rests on the ground for 0.2 sbefore the other leg begins its swing. The length of the leg, from hip to heel, is 0.90 m.

At what speed does this student walk? (Think carefully about how far forward the student moves at each step.)

The swinging leg reaches its maximum speed at the bottom of its arc. How many times faster is this maximum leg speed (measured with respect to the ground) than the average walking speed?vmax,groundvwalk = ?
