Question : basic projectile motion

Hi

The following question is about projectile motion and is supposed to illustrate the fact that the motion in the horizontal direction is unchanged:

2. Supposing a snowmobile is equipped with a flare launcher which is capable of launching a sphere vertically (relative to the snowmobile). If the snowmobile is in motion and launches the flare and maintains a constant horizontal velocity after the launch, then where will the flare land (neglect air resistance)?

a. in front of the snowmobile
b. behind the snowmobile
c. in the snowmobile <==answer

I see the point the question is trying to make but where has teh flare got its horizontal motion from? Is it because it was on a snowmobile which was moving horizontally ? I find that a little odd (new concept to me) because it seems as if its the snowmobile that has the horizontal motion, not the flare. I'm sure i'll get used to it. Newton's first law certainly seemed odd when i first heard it 4 months ago (god knows what we did at my school)!

thanks

Answer : basic projectile motion

"Is it because it was on a snowmobile which was moving horizontally ? I find that a little odd (new concept to me) because it seems as if its the snowmobile that has the horizontal motion, not the flare"
it is because the snowmobile was moving horizontally. The flare was part of the snowmobile before launching so it partook of the snowmobile motion
