Problem: The figure is the position-versus-time graph of a jogger.A. What is the jogger’s velocity at t = 10 s? B. What is the jogger’s velocity at t = 25 s? C. What is the jogger’s velocity at t = 35 s?

FREE Expert Solution

Velocity:

v=xt

This shows that the slope of the position-versus-time graph gives the velocity of the jogger.

A.

At t = 10s, we'll consider the slope of the first part of the motion between 0s and 20s.
