1. The problem statement, all variables and given/known data A helicopter flies upward at 3.0m/s. The pilot drops a coke bottle when the helicopter is 30.0m above ground. How long will it take the coke bottle to hit the ground? (2.8s) *Note* We can't factor or use quadratics to solve 2. Relevant equations 3. The attempt at a solution First I tried to calculate the distance the coke bottle will go upward before falling downward: Vf2-Vi2/2a = d 9/19.62 0.459 Then I added that to the distance... D(total) = 0.459m + 30.0m = 30.459m Then I attempted to find the time from there using the formula: d = vi(t) + 1/2 a t(squared) Vi from the maximum height (Total distance) is zero so Sqrt(2d/a) = t Sqrt(60.918/9.81) Sqrt(6.20978) t = 2.4919 = 2.5s Im off by .3 please help!
