7. A formula 1 racecar is capable of very quick starts (with a launch control system, that prevents the wheels from spinning during rapid acceleration)). A 2011 Ferrari (driven by none other than Agent 001) is initially at rest, and undergoes a constant acceleration of 14 m/s^2 while in first gear. The car shifts to the second gear and has a constant acceleration of 13 m/s^2. While in second gear, the car travels 55m in 1.2 seconds before shifting to third gear. While in third gear, the acceleraton f the car is 9 m/s^2, and the car travels a distance of 35 m. Calculate
a) total distance
b) the total time
c) the final speed of the car
