Question

How long it take to change the velocity of a car from 100m/s to 250m/s if it accelerates at 5m/s^2​

Answer 1

30 seconds

Step-by-step explanation:

The formula for calculating acceleration is

( final velocity - inital velocity) ÷ time

If we enter the values, it would be (250 - 100) ÷ t = 5m/s^2

Now we need to know 't'

So we rearrange the equation to make t the subject.

(250-100) ÷ 5 = 30s
