Question

the question give the positions s = ƒ(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? s = 25/t2 - 5t, 1≤ t ≤ 5
