The initial velocity is 0. Round the value of acceleration and your answer to 2 decimal places. ive tried figuring this question out in so many ways but im not getting the right answer, any help is greatly appreciated

Assuming no air resistance and 0 initial velocity, the equation is d=(at^2)/2 where t is time, d=distance, and a is acceleration (ft/sec^2). You should be able to figure it out.
