If acceleration is calculated using the equation, "change in velocity/change in time,"

what is the acceleration of an object traveling + 120cm/s in 12s?

0.1m/s^2

Explanation:

Acceleration = change in velocity / change in time

Initial velocity u=0

Initial time=0

a=v-u/t2-t1

a=1.2-0/12-0

a = 1.2/12 = 0.1m/s^2

Changing to meter per second:

120cm/s = (120/100) = 1.2m/s,

Therefore, acceleration=0.1m/s^2.
