Answer 2

Answer:

7.5m/s^2 is the answer to ur question

Explanation:

Initially the car was at rest

So initial velocity of the car(u)=0

finally he was moving with a velocity of 54km/h=54×5/18 m/s=15 m/s

So final velocity of the car(v)=15m/s

Time taken to change the velocity =2 seconds

ACCELERATION =V-U/T

=15m/s-0/2

=15m/s/2seconds

=7.5m/s^2
