Question

When brakes are applied on a moving vehicle it stops after travelling a distance is called stopping distance Write an expression for stopping distance

Answer 1

Answer:

s=u^2/2a

Explanation:

We know

v^2 - u^2 = 2as

As the car will stop, so final velocity i.e. v=0

Also, acceleration is retarding so a= -a

Now,

(0)^2 - u^2 = 2as

-u^2 = -2as

s = u^2/2a

Hope this helps.
