Question
A particle's position is given by x = 6.00 - 15.00t + 3t2, in which x is in meters and t is in seconds.
(e) Is there ever an instant when the velocity is zero? If so give the time t; if not answer "0."
(f) Is there a time after t = 3 s when the particle is moving in the negative direction of x? If so give the time t; if not answer "0."
