Question

a car starts from rest and attains a velocity of 18 metre per second in 2 second find the acceleration???​

Answer 1

Answer:

PLEASE MARK AS BRAINLIEST

9m/s^2 is the acceleration

Explanation:

v=u+at is the formula for the question

as given u is 0,as it is at rest initially

and finally it gets velocity of 18m/s

in time=2sec

so,

=18=0+a(2)

=18=a(2)

=18=2a

=18/2=a

=9=a

Answer 2

Answer:

9 metre per second square

Explanation:

intial velocity=0m/s

final velocity,v=18m/s

time =2s

acceleration,a=v-u/t

                    =18-0/2

                    =18/2 =9m/s square
