A car starts at a position of x=6 ft and has a speed of 7 mph. After 24 s the car has a speed of 40 mph. Determine the magnitude of the car's average acceleration during this time.

1 answer

7 mph = 10.267 ft/s
40 mph = 58.667 ft/s
acceleration = 48.40/24 = 2.017 ft/s^2

That's pretty slow accelerationm.. less that 0.1 g

The initial position does not matter.
