An experiment was performed on a 2kg block. Forces 5, 10, and 15 Newton's respectively were applied to the block for 5 seconds. Describe the difference in acceleration between the three trials?

B) The final acceleration will triple between the first and third trial.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
