The position of a body moving on a coordinate line is given by s = {2 – + + 2 for 0 St < 4, with s in meters and t in seconds. (a) Find the body's displacement and average velocity for the given time interval. Displacement = m Average velocity = m/s (b) Find the body's velocity at the endpoints of the interval. Velocity at t = 0 is m/s Velocity at t = 4 is m/s (c) Find the body's acceleration at the endpoints of the interval. Acceleration at t = 0 is m/s2 Acceleration at t= 4 is m/s2 (d) When, if ever, during the interval does the body change direction? If there is more than one answer, enter a comma separated list. If the body never changes direction during the interval, enter NONE. te S
