A body moves on a coordinate line such that it has a position s f(t)t2-5t+4 on the interval 0sts4, 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? The body's displacement for the given time interval ism. (Type an integer or a simplified fraction.)
