A plane is flying horizontally with speed 292 m/s at a height 3880 m above the ground, when a package is dropped from the plane.

the acceleration of gravity is 9.8 m/s 2 . neglecting air resistance, when the package hits the ground, the plane will be 1. ahead of the package. 2. directly above the package. 3. behind the package. 008 (part 2 of 4) 10.0 points what is the horizontal distance from the release point to the impact point?

The plane is straight above the package when it hits the ground. 
Find in what way long a free fall from a height of 4240 m takes: s = 1/2 gt^2 
t^2 = 2s/g 
t^2 = 2* 3880/9.8 = 791.8367
t = √791.8367
t = 28.1396 seconds 
Now find the horizontal displacement with v = 292 m/s in 28.1396 s: 
s = v*t 
s = 292 * 28.1396 = 8216.76 m

tiny-mole [99]
Magnets don’t need to touch each other in order to be magnetic because all objects have an attraction however, the closer the magnets get, the more magnetic it is.
