The position of the front bumper of a test carunder microprocessor control is given by x(t) = 2.17 m +(4.80 m/s?)r2 – (0.100 m/s")t. (a) Find its position and accel-eration

at the instants when the car has zero velocity. (b) Draw x-t,vg-t, and az-t graphs for the motion of the bumper between t = 0and t = 2.00 s.
