Question

In 8.0 seconds a truck accelerates 5.7 m/s² to 57.7 m/s. How fast was the car going before it accelerated? (Round to one decimal place ex

14.1)

Answer 1

12.1 m/s

Step-by-step explanation:

If the car is gaining 5.7 meters per second of speed for 8 seconds then we need to multiply 5.7 by 8. this gives us 45.6

Now all we need to do is subtract 45.6 from 57.7. This is 12.1
