Three bullets are fired simultaneously by three guns aimed toward the center of a circle where they mash into a stationary lump. the angle between the guns is 120°. two of the bullets have a mass of 3.90 x 10⁻³ kg and are fired with a speed of 368 m/s. the third bullet is fired with a speed of 618 m/s and we wish to determine the mass of this bullet.

Explanation:

Given

mass of first and second bullet

Velocity of two bullets

velocity of third bullet

angles between guns is

Suppose First gun is at and second is at and third is at

therefore

conserving momentum in x-direction

as three bullets club together to become lump

1 the 4 is sig

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
