Question

A race car accelerates on a straight track from 0 to 200 km/h in 6s.
Another race car accelerates from 0 to 100 km/h in 5s. Compare the velocities and accelerates of the cars

(200-0)/6 = 33.33 km/sh
(100-0)/5 = 20 km/ s h

so the acceleration of the first one is 33.33/20 = 1.67 times the second one
velocity = acceleration * time
first car v in km/h = 33.33 * t in seconds
second car v in km/h = 20 * t in seconds
