Horizontal Projectile Motion

The initial horizontal velocity of a projectile is ____ its final horizontal velocity.

• less than

• equal to

• greater than

Victor Velocity is standing on top of the roof of his house, firing stones with his slingshot over a level field. He is aiming straight outward, horizontally. If Victor pulls back harder on the sling to shoot a stone, which of the following quantities will be changed?

• The vertical displacement of the stone.

• The distance the stone travels, and the horizontal velocity.

• The time it takes the stone to strike the ground, and the horizontal velocity.

What is the horizontal acceleration of a projectile?

• 0 m/s²

• 9.8 m/s²

What is true about the vertical velocity of a projectile launched horizontally?

• It is initially at its maximum value.

• It increases due to gravity as it falls.

• It remains constant throughout its trajectory.

• It decreases as it falls due to gravity.

What is the effect of increasing the initial horizontal velocity on the range of a horizontally launched projectile?

• The range decreases.

• The range remains the same.

• The range increases.

• The range becomes zero.

A projectile is launched horizontally from a 100-meter high platform. If the initial speed is doubled, how does the range change?

• The range is halved.

• The range remains the same.

• The range doubles.

• The range quadruples.

• 28.0 m/s

• 39.6 m/s

• 44.3 m/s

• 56.0 m/s

• 30.0 meters

• 45.0 meters

• 60.0 meters

• 90.0 meters
