Question

How can I calculate the average acceleration?

Answer 1

`v_(f) = final velocity`


`v_(o) = initial velocity`


`t_(f) = final time`


`t_(o) = initial time`


`a = average acceleration`


`a = ((v_(f)-v_(o)))/((t_(f)-t_(o)))`

Answer 2

Average acceleration =
(change in speed over some time) / (time for the change)
(could be positive or negative)

Change in speed = (speed at the end) - (speed at the beginning)
(could be positive or negative)

Time for the change = (time at the end) - (time at the beginning)
(always positive)
