Describe 7 non-experimental methodologies and a precaution? ?

An object accelarates from rest to a velocity of 2.4m/s over a distance of 16m what was its accelaration

Hurry: the angle measures associated with which set of ordered pairs share the same reference angle? (-square-root 3/2, 1/2) , (-1/2, -square-root 3/2) (1/2, -square-root 3/2) , (-square-root 3/2, 1/2) (-1/2, -square-root 3/2), (1/2, square-root 3/2) (square-root 3/2, 1/2) , (1/2, square-root 3/2)

And intervening opportunity is an example of
