The position of the front bumper of a test car under microprocessor control is given by x 1t2 = 2.17 m + (4.80 m/s2)t2 - (0.100 m/s6)t6. (a) Find its position and acceleration at the instants when the car has zero velocity. (b) Draw x-t, vx-t, and ax-t graphs for the motion of the bumper between t = 0 and t = 2.00 s.
