1. The problem statement, all variables and given/known data The height of a helicopter is given by h=3.00t^3, where h is in meters and t in seconds. After 2s, the helicopter releases a small bag. How long does it take for the bag to reach the ground? Xi = 0 Xf = 24 (i got 24 meters when i plugged in seconds in h=3.00t^3) A(gravity) = 9.81 Vi = 0 2. Relevant equations Xf=Xi+Vi(t)+1/2at^2 3. The attempt at a solution i plugged in the numbers 24=(t)+1/2(9.81)(t^2) 24=(t)+4.905(t^2) 19.095=t^3 this is where i am stuck because i dont know how to solve an equation with a letter cubed... i dont know if im doing this right, help?
