If the velocity of a car in increased by 20%, then the minimum distance in which it can be stopped increases by:

A

0.44

B

0.55

C

0.66

D

0.88

Text Solution

Verified by Experts

The correct Answer is:
a
Here`0^(2)-v^(2)= -2aS` or `v^(2)propS`
or `S/S=(1+(20)/(100))^(2)=(36)/(25)`
or `((S)/(S)-1)xx100=((36)/(25)-1)xx100`=44%
