Average acceleration = (change in speed) / (time for the change) = (60 - 0) / (2.1) =
28.571 miles per hour per second, or
41.905 feet per second2
Using: (1 mile / hour - second) x (5,280- ft / mile) / (3,600 second / hour) = 1.4666 ft/sec2
14.19 feet per second2 (rounded)
Acceleration = -20 mi/h^2
Acceleration = (change in speed) divided by (time for the change)Acceleration = (25 - 0)/(3) = 81/3 miles per second2Don't try this at home. That acceleration is about 1,368 G's. You can not survive it!
The acceleration cannot be determined with this information. The beginning and ending velocity needs to be known. You can determine her average velocity, however. average velocity = displacement/time = (9mi - 3mi)/3s = 6m/3s = 2m/s
60/5 = 12 miles per second2

Acceleration= distance / velocity squared
Acceleration = -20 mi/h^2
Acceleration = (change in speed) divided by (time for the change)Acceleration = (25 - 0)/(3) = 81/3 miles per second2Don't try this at home. That acceleration is about 1,368 G's. You can not survive it!
Not sure of your abbreviations. I'll assume that 'ms' = "meters per second", and 's' = "seconds" Change in speed = (25 - 0) = 25 meters per second Time = 8 seconds Average acceleration = (change in speed) / (time) = 25/8 = 3.125 meters per second2
-10 mph/sec

Something that has a constant acceleration of 13.3 per second squared
60/5 = 12 miles per second2
minus a trunk and brick wall.
