The velocity of a car increases by 40 m/s in 80 seconds. What is the acceleration of the car

Given that the velocity of a car increases by 40 m/s in 80 seconds, the acceleration of the car will be given by:

a = (final velocity-initial velocity) / (time)

thus;

final velocity=40 m/s

initial velocity=0

time=80 seconds

hence;

a = (40-0) / 80

=0.5m/s^2
