This is my first post here so please bear with me if I'm doing something wrong 1. The problem statement, all variables and given/known data A cargo plane is flying horizontally at an altitude of 10.1 km with a speed of 910 km/h when a large crate falls out of the rear loading ramp. (Ignore any effects due to air resistance.) How long does it take the crate to hit the ground? I converted everything to meters. Yf = 0m Yi = 10100m Yxi = 252.78 m/s g = -9.81 m/s 2. Relevant equations Xf = Xi + Vxi*t Yf = Yi + Vyi*t - 4.905(t)^2 3. The attempt at a solution My problem is figuring out Vyi in this case so that I can plug it into my second equation to solve for time. Can anyone give me a push in the right direction?
