Physics 2-5 - How projectiles move

Which angle will produce the greatest range (in the absence of air resistance)?

• 0 degrees
• 45 degrees
• 90 degrees
• none of these

Which angle will produce the greatest height (in the absence of air resistance)?

• 0 degrees
• 45 degrees
• 90 degrees
• none of these

Can you pass Physics if you never study?

• Yes
• No

Two identical objects are launched from a cannon. Object A leaves the cannon at 25 m/s, Object B leaves the cannon at 15 m/s. Which object will have the greatest height?

• The faster object A will go higher
• The slower object B will go higher
• Both will go the same height
• Depends on how much gunpowder was used

Two identical objects are launched from a cannon. Object A leaves the cannon at 25 m/s, Object B leaves the cannon at 15 m/s. Which object will hit the ground first?

• The faster object A will hit the ground first
• The slower object B will hit the ground first
• Both will take the same time
• Depends on how much gunpowder was used

Which component of velocity is changing for a projectile? (in other words, which direction has acceleration happening)

• The x component (horizontal velocity)
• The y component (vertical velocity)
• Both change
• Neither change

Two identical objects are launched from the ground at 5 m/s. Object A has a launch angle of 45, while Object B has a launch angle of 65. Which object has the greatest maximum height?

• A
• B
• Both objects reach the maximum height
• unable to determine with the given information

Two identical objects are launched from a cannon. Object A leaves the cannon at 25 m/s, Object B leaves the cannon at 15 m/s. Which object will have the greatest range?

• The faster object A will go further
• The slower object B will go further
• Both will go the same distance
• Depends on how much gunpowder was used
