Need help with this question, dunno what to do. Please help me
The position function of an object that moves in a straight line is . Calculate the maximum and minimum velocities of the object over the given time interval.
note that for all values of t in the given interval .
to find the max and min velocity ...
therefore, is a maximum at
is the maximum velocity in the given interval.
the minimum velocity would occur at one of the two endpoint times ( or ) if they are included in the interval.
recheck the given interval to see if it is really .
