[See Steps] A body moves on a coordinate line such that it has a position s = f(t)=t^2-5t+4 on the interval 0 < t < 7, with s in meters and t in seconds.
Question: A body moves on a coordinate line such that it has a position s = \(f\left( t \right)={{t}^{2}}-5t+4\) on the interval 0 < t < 7, with s in meters and t in seconds.
- Find the body's displacement and average velocity for the given time interval
- Find the body's speed and acceleration at the endpoints of the interval
- When, if ever, during the interval does the body change direction?
