How long does a car accelerating at 9ms take to travel 100m?

Answer 1

At 25 meters per second a car will travel 100 meters in 4 seconds and 1000 meters in 40 seconds.

Answer 2

Using the formula ( d = v_i t + \frac{1}{2} a t^2 ) to find the time taken, where ( d = 100 , \text{m} ), ( v_i = 0 , \text{ms} ), and ( a = 9 , \text{ms}^2 ), we get ( t \approx 4.71 , \text{s} ).

Answer 3

Roughly 4.13 s
