Marco wants to buy the used sports car with the greatest acceleration.
Car A can go from 0 m.s-1 to 18,9m.s-1 in 4,00 s. Car B can accelerate from 0 m.s-1 to 22,4 m.s-1 in 3,50 s. Car C can go from 0 to 26,8 m.s-1 in 6,00 s. Rank the three cars from greatest
acceleration to least.
Car B
Car A
Car C
