Which statements describe projectile motion? Check all that apply.
- Projectile motion is a combination of horizontal and vertical motion. - The horizontal and vertical motions of a projectile are independent.
Which are examples of projectile motion? Check all that apply.

Austin kicks a soccer ball with an initial velocity of 18.0 m/s at an angle of 35.0°. What are the horizontal and vertical components of the initial velocity? Round your answers to the nearest tenth.
vix = ⇒ 14.7 m/s viy = ⇒ 10.3 m/s
Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. How long will the ball be in the air before it lands? Round your answer to the nearest tenth. ⇒ 1.2 s How far will the football travel before it lands? Round your answer to the nearest tenth. ⇒ 15.1 m
⇒ 1.2 s ⇒ 15.1 m
A tornado lifts a truck 252 m above the ground. As the storm continues, the tornado throws the truck horizontally. It lands 560 m away from where it was picked up. How fast was the truck traveling horizontally through its flight? Round your answer to the nearest tenth.
78.1 m/s
Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. You have determined that the football would travel 15.1 m before landing. How would this value change if the football was kicked at an angle of 35.0°?
If the football is kicked at a 35.0º angle, it will travel 18.2 m before landing. This is farther than if it were kicked at a 25° angle.
A rock is thrown horizontally at a speed of 5.0 m/s from the top of a cliff 64.7 m high. The rock hits the ground 18.0 m from the base of the cliff. How would this distance change if the rock was thrown at 10.0 m/s?
If the rock was thrown at 10.0 m/s, the rock would land twice as far from the cliff as it did previously.
Which statement describes the horizontal acceleration of a projectile?
It is zero.
Use the drop-down menu to complete the sentence. The initial horizontal velocity of a projectile is ________ its final horizontal velocity.
equal to
