A car accelerates uniformly from rest to a speed of 40 mi/h in 10 s.
Find the acceleration and distance the car travels during this time.
We know that acceleration is the change in velocity divided by the time the change takes. So in this case, we have 40 mi/h divided by 10 seconds. To make our units compatible, we note that 40 mi/hr = 0.1112 mi/second. SO, 0.1112 mi/s divided by 10 s gives us an acceleration of 0.01112 mis^(-2).
