Projectile Motion Practice

The more mass an object has, the faster it will fall.

• True
• False

If you throw a baseball straight up, what is its acceleration at the highest point?

• 9.8 m/s²
• 9.8 m/s
• 0 m/s²
• 0 m/s

If you throw a baseball straight up, what is its velocity at the highest point?

• 9.8 m/s²
• 9.8 m/s
• 0 m/s²
• 0 m/s

What is the horizontal acceleration of a projectile?

• 0 m/s²
• 9.8 m/s²

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

An object is shot from the ground (at 25 m/s) at 25 degrees and 65 degrees.  Which one has the greater range?   (assume no air resistance)

• 25 degrees
• 65 degrees
• same for both

An object is shot from the ground (at 25 m/s) at 25 degrees and 65 degrees.  Which one rises to a higher height? (assume no air resistance)

• 25 degrees
• 65 degrees
• same for both

An object is shot from the ground (at 25 m/s) at 25 degrees and 65 degrees.  Which is in the air for longer? (assume no air resistance)

• 25 degrees
• 65 degrees
• same for both

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

In the picture, cannonball A was launched at 10 m/s at 60°, and B was launched at 18 m/s at 25°. The cannonball that hit the ground first was

• A, because it had less total velocity.

• B, because it had more total velocity.

• A, because it had less initial vertical velocity.

• B, because it had less initial vertical velocity.
