Answer:
3.128 m/s^2
Step-by-step explanation:
Acceleration is the change in velocity over the change in time. Final velocity is 42 mph and initial velocity is 0 mph, but we need to convert these values to meters per second (m/s).
To do that, we divide 42 by 2.237 and the result is 18.77.
Now we can calculate the change in velocity: 18.77 - 0 = 18.77 m/s.
Now we need the change in time: 6 s is the elapsed time, 0 s in the starting time. So 6 s - 0 s = 6 s.
Now we divide 18.77 by 6 s and obtain the answer, which is:
18.77 m/s ÷ 6 s = 3.128 m/s^2
