A car accelerates steadly from zero to 30m/s in a distance d & a time t, another car takes a time 3t to accelerate steadly from stationary to the same final velocity.what distance does the second car cover during the new the new acceleration?
The second car has 1/3 of the acceleration of the first car.
In the same length of time, the second car travels 1/3 as far.
If they both travel to the same final velocity, the second car travels 3 times longer (in time), and goes (1/3)*3^2 or 3 times a far as the first car.
The distance travelled is 3d.
