Homework Statement
There was a plane with the height of 1 km above the ground. The plane is moving horizontally 200 m/s and can fire a bullet with the velocity of 400 m/s. At one time, the the gun form an angle of 37(degree) and fired the bullet.
I was confused with the horizontal (x-axis) velocity of the bullet. Does the velocity of the plane firing the gun also relevant or does it not ?
Homework Equations
The equation for the horizontal velocity of the bullet should be :
Vx = Vo. Cos37
The Attempt at a Solution
So it should be
Vx = Vo. Cos37 = 319.45 m/s
If the plane is moving 200 m/s horizontally. Does it add up with the horizontal velocity of the bullet? Like for say the total horizontal velocity of the bullet is 319.45 m/s + 200 m/s = 519.45 m/s .
Can someone explain it to me ? Sorry for asking such trivial question
