Upward Launch Projectiles

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

• True
• False

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

What is the vertical acceleration of a projectile?

• 0 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

Consider drops of water leaking from a water faucet. As the drops fall they 

• remain at a relatively fixed distance from each other
• get farther apart
• get closer together

Two objects of the same mass are launched from the ground. Object A has a launch angle of 45, while Object B has a launch angle of 65. Which object has the greatest maximum height height?

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

Two objects of the same mass are launched from the ground. Object A has a launch angle of 45, while Object B has a launch angle of 65. Which object will hit the ground first?

• A
• B
• Both objects hit the ground at the same time

A projectile is launched from a height with an initial velocity v_0,x. The v_f,x represents the final horizontal velocity before impact.

• v_0,x = v_f,x
• v_0,x < v_f,x
• v_0,x > v_f,x
• unable to determine

The shape of the path a projectile follows...

• circular
• linear
• wavy
• parabolic
