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.

mistakes are ok

im sorry i dont know
