• True
• False

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

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

In the absense of air resistance, as an object travels through the air, its horizontal velocity

• changes continuously
• not enough information
• remains the same

If I throw a crayon straight up at 12 m/s, how fast is its velocity when I catch it at the same height?

• -6 m/s
• -12 m/s
• -18 m/s
• -24 m/s

What is the height of a horizontal projectile if it takes 3 seconds to hit the ground?

• 3.00 m
• 29.4 m
• 44.1 m
• 88.3 m

Projectile A is fired with a velocity of 20 m/s off a 20 m tall cliff, while projectile B is fired with a velocity of 40 m/s off a 20 m tall cliff. Which statement best describes the time of flight of projectile B as compared to projectile A?

• Projectile B is in the air a longer time than projectile A,

• Projectile B is in the air less time than projectile A.

• Projectile B in the air for the same amount of time as projectile A.

• Can not be compared.
