An automobile is traveling 65km/h the brakes decelerate it at a rate of -6.0 m/s^2 how long will it take to stop the car?

Explanation:

It is given that,

Initial speed of the automobile, u = 65 km/hr =

Final speed of the automobile, v = 0

Deceleration of the automobile,

We need to find the distance covered by the car as it comes to rest. It can be calculated using third equation of motion as :

So, the acceleration of the car is . Hence, this is the required solution.

pe = weightxheight = 2000x1000=2,000,000joules
