A bomber flies horizontally with a speed of 323 m/s relative to the ground. The altitude of the bomber is 3580 m and the terrain is level. Neglect the effects of air resistance. The acceleration of gravity is 9.8 m/s 2 . How far from the point vertically under the point of release does a bomb hit the ground? Answer in units of m.

Respuesta :

Answer:8730.63 m

Explanation:

Given

Bomber velocity [tex]u=323 m/s[/tex] relative to ground

Altitude of the bomber [tex]h=3580 m[/tex]

Range of bomb when bomb when it is released is given by

[tex]R=u\times t[/tex]

where [tex]u =velocity\ of\ Bomber[/tex]

Horizontal velocity of bomber is equal to bomb horizontal velocity

time taken by to cover 3580 m

[tex]h=ut+\frac{at^2}{2}[/tex]

[tex]3580=0+\frac{9.8\times t^2}{2}[/tex]

[tex]t^2=\frac{7160}{9.8}[/tex]

[tex]t=27.03 s[/tex]

Therefore range of bomb is

[tex]R=323\times 27.03=8730.63 m[/tex]

Therefore bomber must release the bomb at a horizontal distance of 8730.63 m before the hit point
