(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A cargo plane flying horizontally at an altitude of 13.9 km with a constant speed of 508 km/hr when a large crate slides out of the rear of the plane

Assume the acceleration of gravity is 9.81 meters/seconds squared.

1)How long does it take for the crate to hit the ground?

2)What is the horizontal distance of the crate from the point it fell off to the point where it hits the ground?

3)How far is the crate from the airplane when the crate hits the ground assuming the plane remains at a constant speed?

2. Relevant equations

The golden three:

Vf = Vi + (A)(T)

Vf^2 = Vi^2 + 2(A)(D)

D = (Vi)(T) + 1/2(A)(T^2)

(sorry i don't know how to do the squared simbol)

3. The attempt at a solution

First, I drew a diagram of what is described in the problem. We were also talk to make a chart and fill in the values. Once i know what the values are for the charts, i will be able to solve the problem(it is multiple parts). I only need help in solving the values for the charts. The chart is as follows:

Vertical(y)__________Horizontal(x)

Vi- 0 ______________Vx- ?

Vf- ? ______________Dx- ?

A-(-9.8m/s)_________T-?

D- 13.9km

T-?

I know that time is constant on both, and i think i have all the given info in the charts, but i don't really know what to do after this. Please, if anyone could help that would be great, thanks
