Question

Calculate the time (in seconds) needed for a car to accelerate from 0 m/s to 25 m/s at 5 m/s^2?

Answer 1

Car will take 5 sec to reach from 0 m/sec to 25 m/sec

Step-by-step explanation:

We have given initial velocity u = 0 m/sec

And final velocity v = 25 m/sec

Acceleration
`a=5m/Sec^2`

From first equation of motion we know that
`v=u+at`, here v is final velocity, u is initial velocity, a is acceleration and t is time

So
`25=0+5* t`

`t=4 sec`

So car will take 5 sec to reach from 0 m/sec to 25 m/sec
