Re: Dropped bomb from flying aircraft
A pilot drops a bomb from a plane flying
horizontally at a constant speed. Neglecting
air resistance, when the bomb hits the ground
the horizontal location of the plane will
A) be behind the bomb.
B) be over the bomb
C) depend on the speed of the plane when
the bomb was released.
D) be in front of the bomb
horizontally at a constant speed. Neglecting
air resistance, when the bomb hits the ground
the horizontal location of the plane will
A) be behind the bomb.
B) be over the bomb
C) depend on the speed of the plane when
the bomb was released.

h = ho.d - o.5g*t^2 = 0نوری نیرو نوشته شده:A bomb is dropped from a plane flying at 4000 meters. The plane is flying at 80 m/s. How far, in a horizontal direction, did the bomb hit the ground?
4000 - 4.9t^2 = 0
-4.9t^2 = -4000
t^2 = 816.3
Tf = 28.6 s. = Fall time or time in flight.
Dx = Hor = 80m/s * 28.6s = 2286 m.
Talk slowly but think quickly
Spend some time alone
When you realize you've made a mistake, take immediate steps to correct it
BEGIN while others are procrastinating
COMMEND while others are criticizing
PREPARE while others are daydreaming
To handle yourself, use your head; to handle others use your heart.
