The horizontal component of a projectile's velocity is independent of...

• it's range
• time
• the vertical component
• none of these

In the absence of air friction, the horizontal component of a projectile's velocity doesn't change as the projectile moves. 

• True
• False
• Sometimes true
• Sometimes false

At the instant a ball is thrown horizontally with a large force, an identical ball is dropped from the same height. Which ball hits the ground first? 

• Neither- they hit at the same time
• the horizontally thrown ball
• the dropped ball
• None of these
