Projectile Motion Worksheet

An object is thrown into the air and follows the path represented in the diagram below. Which of the following vectors best represents the acceleration of the object at point A?

A ball is thrown horizontally at a speed of 20. meters per second from the top of a cliff. How much time, to the nearest tenth of a second, does the ball take to fall 19.6 meters to the ground? $$T=\sqrt{\frac{2D}{G}}$$

A book is pushed with an initial horizontal velocity of 5.0 meters per second off the top of a desk. What is the initial vertical velocity of the book?

Part 1. A boy standing at the edge of a sheer cliff 45 meters above the level ground throws a baseball horizontally at 25 meters per second. How long until it hits the ground? Use the formula $$t = \sqrt{\frac{2d}{g}}$$ .

Part 2. How far from the edge does it hit the ground? Use the relation $$d = v t$$ .

A baseball player throws a ball horizontally. Which of the following statements best describes the ball's motion after it is thrown?

A softball is thrown straight up, reaching a maximum height of 20 meters. What is the ball's approximate speed when it hits the ground?

Which of the following is true about a freely falling object near Earth's surface?

A basketball player jumped straight up to grab a rebound. If she was in the air for 0.80 second, how high did she jump, to the nearest hundredth of a meter? Use $$y=\frac{gt^2}{2}$$ and assume constant gravitational acceleration near Earth. **REMEMBER ITS 1/2 THE TIME TO THE PEAK!

A plane flying horizontally above Earth's surface at 100 m/s drops a crate. The crate strikes the ground 30.0 seconds later. What is the magnitude of the horizontal component of the crate's velocity just before it strikes the ground? Neglect air resistance.
