All right, so let's say we have a rescue plane like this, and it's traveling with the speed of 43 meters a second, and it drops a package from a height of, let's see, 150 meters.
00:17
And so we want to know what is the horizontal distance the package travels for part a, or i guess part one.
00:27
So delta x here is just going to be the speed that it leaves the plane, which is the speed of the plane, time.
00:33
The time it's in the air.
00:35
So this will be v times the square root of 2h over g, where 2h over g is our time intervals.
00:41
So 300 divided by 9 .8, take the square root, multiplied by 43.
00:46
This should be 237 .9 meters...
