Characteristics of Projectiles Quizizz

Supposing a snowmobile is equipped with a flare launcher that 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)?

• in front of the snowmobile

• behind the snowmobile

• in the snowmobile
