Homework Statement


An airplane is dropping an aid package in a remote area. The plane is moving horizontally at speed 0 and the package lands a horizontal distance from where it was released by the plane.

a) Find the time it takes for the package to land. -This is were I'm having the problem and is mostly what is preventing me from doing the rest.

b) Find the altitude of the plane.

c) Find the velocity (vector) of the package when it lands.

d)Find the speed of the package when it lands.

Write your results in terms of 0, L, and g. Check the units/dimensions for each answer.


Homework Equations


x=(-g/2)t2+V0t+x0
v=-gt+V0
a=-g

The Attempt at a Solution


The acceleration in the y-vector is -g/2*t2 and it has an initial velocity of 0 because it is being dropped from a plane moving parallel to the ground. solving for t gave me t=(2X0/g)1/2 then solving for X0 I got X0=v2/2g which is just leading me in circle leaving me with variables that I can't find a value for and are not accepted in the answer.
