Exercises 1–6 give the positions s = f(t) of a body moving on a coordinate line, with s in meters and t in seconds.a. Find the body’s displacement and average velocity for the given time interval.b. Find the body’s speed and acceleration at the endpoints of the interval.c. When, if ever, during the interval does the body change direction?

Solution:Step 1 of 4:In this problem, a. We have to find the body’s displacement and average velocity for the given time interval.b.We have to find the body’s speed and acceleration at the endpoints of the interval.c. does the body change direction
