Horizontally Launched Projectile Quiz 23

What is a horizontally launched projectile?

• An object launched with a vertical velocity

• An object launched with a horizontal velocity

• An object launched at an angle

• An object launched with no initial velocity

In the given example of a cliff diver, what is the initial velocity in the x direction?

• Five meters per second

• Zero meters per second

• Unknown

• Thirty meters per second

What is the displacement in the y direction for the cliff diver?

• Positive 30 meters

• Negative 30 meters

• Zero meters

• Unknown

What is the acceleration in the y direction for a freely flying object?

• Zero meters per second squared

• Negative 9.8 meters per second squared

• Unknown

• Positive 9.8 meters per second squared

What is the initial velocity in the y direction for a horizontally launched projectile?

• Zero meters per second

• Five meters per second

• Unknown

• Thirty meters per second

What is the time it takes for the cliff diver to displace 30 meters vertically?

• Unknown

• 9.8 seconds

• 5 seconds

• 2.47 seconds

What is the formula used to calculate the displacement in the x direction?

• delta x = v initial in the x direction + v final in the x direction

• delta x = v initial in the x direction * time

• delta x = v final in the x direction * time

• delta x = v initial in the x direction / time
