Here we have a package, we have a plane flying horizontally above the ground.
00:05
After a package is dropped from the plane, how long will it take for each to reach c level from the time it is dropped? assume that the package is like the plane has an energy velocity of 360 kilometers per hour and the horizontal direction.
00:18
So first thing we'll do is to go into the vertical direction.
00:25
This represents the vertical direction and we're going to use the equation.
00:29
One to find the time, so we're going to use s is equal to ut plus half, at squared.
00:39
Where s is displacement, which is the vertical displacement.
00:42
That will be the height of the plane above the ground level.
00:48
And u is the inch of velocity in the vertical direction.
00:51
The time it takes to fall to the ground is the acceleration in the vertical direction.
00:58
We're not given the height instead of we're given h.
01:01
So i'm going to let's up to see that we h is equal to the initial velocity in the vertical direction of buzer because it's dropped in the vertical direction...
