Answer 1

HEY BUDDY....

HERE IS UR ANSWER...

________________________

A.T.Q.

v ( final ) = 0

u = 126 km / h

s = 245 m

We know

=> v^2 = u^2 + 2as

=> 0 = 126 × 126 + 2 × 245 × a

=> a = - 15876 / 490

=> a = - 32.4 m / s^2

Now ,we know

=> s = u t + 1/2 at^2

Now brother...

U can calculate time by putting all the values....

and to covert it in second divide it by 3600

HOPE HELPED...

Wish u success...
