A car starts from rest at t = 0 s, and speeds up with a constant acceleration of 1.66 m/s2 for 6.00 s. Then it continues with a uniform speed for another 6.00 s. Finally, it speeds up with a constant acceleration of 2.17 m/s2 until it reaches a speed of 18.0 m/s. (a) Draw the velocity vs. time and acceleration vs. time graphs for this motion. Numerical values on the graphs are not required. (b) How long does it take for the car to reach a speed of 18.0 m/s? Time is measured from the beginning at t = 0 s   (c) What is the total displacement of the car?
