A plane is flying horizontally with speed 167 m/s at a height 4040 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:

Respuesta :

Answer:

The plane will be 4795.23 meters from where he threw the package.

Explanation:

Data:

v = 167 m/s

h = 4040 m

g = 9.8m/s²

package:

after it is dropped there is no horizontal force, so...

[tex]X - Xo = Vt[/tex]

t = [tex]\frac{X - Xo}{V}[/tex]  I

in the vertical we have only [tex]P = mg[/tex]

[tex]Y - Yo = Vot -\frac{gt^{2} }{2}[/tex] but Vo = 0 because the package is dropped

[tex]Y - Yo =-\frac{gt^{2} }{2}[/tex]  II

replacing I in II

[tex]Y - Yo =-\frac{g(X - Xo)^{2} }{2V^{2}}[/tex]

[tex]0 - 4040 =-\frac{9.8(X - Xo)^{2} }{2*167^{2}}[/tex]

X - Xo = 4795.23

The distance from where the plane drops the package and where it hits the ground is the same as the plane flies horizontally, as there is no acceleration at x.
