1. The problem statement, all variables and given/known data A cargo plane is flying horizontally at an altitude of 11.5 km with a speed of 860 km/h when a large crate falls out of the rear loading ramp. (Ignore any effects due to air resistance.) (a) How long does it take the crate to hit the ground? 2. Relevant equations y=y+v(sub y)(t)+1/2a(sub y)(t)^2 v(sub y)=v(initial)(sin58) 3. The attempt at a solution I attempted these equations but since the initial speed of the crate is the same as the plane and there is no angle, I cannot find the y value of velocity, in order to find the time it took to hit the ground.
