Question 1170730: If the arresting device on an aircraft carrier stops a plane in 150 m with an acceleration of -16 m/s2, find the time the plane takes to stop.(Take g=9.81 m/s2) Found 2 solutions by htmentor, Alan3354:Answer by htmentor(1343) (Show Source):
You can put this solution on YOUR website! Combining the formulae v2^2 = v1^2 + 2ad and v2 = v1 + at, with v2=0, we have:
v1 = sqrt(2ad), v1 = at -> t = sqrt(2d/a)
Putting in d = 150 m and a = 16 m/s^2, we get t = sqrt(300/16) = 4.33 s
