PLEASE ASAP! I SENT A PHOTO CHECK AND TELL!

Answer B is the correct "Motion of one projectile as seen from the other is a straight line."

Explanation:

Let's write the equations of motion for each projectile, using that projectile is launched with velocity which has components associated with the angle of launching, given in x and y coordinates as: .

Similarly, assume that projectile b is launched with velocity with components due to the launching angle =

then the equations of motion for the two projectiles launched at the same time (t) from the same spot (position that we assume to be at the origin of coordinates to simplify formulas) are:

therefore, from the frame of reference of projectile "b", the x and y position of projectile "" would be:

 which is linear in "t"

which is also linear in t.

Therefore the motion of one projectile with reference to the other is a straight line (answer B)

Notice as well that this two projectiles cannot collide because they have been launched together, and supposedly at different speeds and angles. The only way that they can share the same x-coordinate and the same y-coordinate at the same time "t" is if their velocity components are equal, which is not what we are told.

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.
