Question

what is the formula for constant acceleration if you know the distance and time?

Answer 1

s=ut+1/2at^2
just put the value.
if initial velocity is zero it becomes s=1/2at^2

Answer 2

what is s?

Answer 3

s is displacement (like distance, but with a direction)

Answer 4

^^that is correct. rearranging for acceleration..\[a= (v-u) /t \]
or \[a=v ^{2}-u ^{2} / 2s\]

Answer 5

"what is the formula for constant acceleration if you know the distance and time?"

Need to have starting (or finishing) speed in there somewhere if ya working out acceleration. Else you will just get average speed
