Question
what was the acceleration of an object between 8 and 10 seconds if velocity at 8 seconds is 10 mi/hr and 0 mi/hr at 10 seconds?

The acceleration, a, is negative because it is decelerating.
Divide the velocity change by 2 seconds. You might want to express the answer in ft/s^2 or g's.
10 mph = 14.67 ft/s
a = -14.67/2 = -7.33 ft/s^2
That equals -0.75 g's
