If a car accelerates from 12 m/s to 60 m/s and it takes 6 seconds to change speeds, what is the car's acceleration? Select the proper formula to find the answer.
• 12 m/s divided 6m/s divided by 6 seconds
• 60m/s times 12m/s divided by 6 seconds
• 60m/s - 12m/s divided by 6 seconds
• 6 m/s - 12 m/s divided by 6 seconds
The correct formula to find the acceleration is:
(60 m/s - 12 m/s) / 6 seconds = 48 m/s / 6 s = 8 m/s^2
So, the car's acceleration is 8 m/s^2.
