Exercises
i give the positions s = f(1) of a body moving on a coor-
dinate 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?
1. s = ? - 31 + 2, 0sIs2
2. s = 61 – f, 0sIS6
3. s = - + 312 - 31, 0 sts3
