A ball is thrown horizontally at a height of 2.2 meters at a velocity of 65 m/s. Assume no air resistance. How far did the ball travel horizontally when it hit the ground?

• 14.3 m
• 30.55 m
• 65 m
• 43.55 m

If a bullet is horizontally shot at the same moment another bullet is dropped from the same height, which will hit the ground first?

• Shot Bullet
• Dropped Bullet
• Hit at Same Time

An object is projected horizontally from a cliff.  The time it takes to hit the ground is

• more than if it was just dropped
• less than if it was just dropped
• the same amount of time than if it was just dropped
• impossible to determine

What can you say about motion in the x and y direction?

• x is dependent on y
• y is dependent on x
• They are dependent on each other.
• They are independent of each other. 

What acts on a projectile in the y direction that causes an object to travel in a parabolic arc?

• Friction
• Gravity
• Tension
• No force acting.
