Answer:
We know that acceleration is the rate of change of velocity per unit time. It is mathematically represented as a= (v-u)/ t . Here a= acceleration, u= initial velocity, v= final velocity and t= time taken. Here u= 0m/s ( since the car is in rest position). v= 12m/s, t=8sec. a=?, Now by using the formula a=(v-u)/t, we get a= (12-0)/8, a= 12/8, a=3/2. Hence the acceleration of the car is 3/2 or1.5m/s^2. Hope this helps you.
