Projectile Motion Practice 1

A projectile is fired from a cannon at a 30-degree angle with the ground and an initial velocity of 100 m/sec. Assuming no air resistance and g = 10 m/s², calculate the time it will spend in the air.

What does the graph in the y vs. t plane represent in terms of vertical motion?

What is the difference between the projectile's path in the absence of gravity and the path influenced by gravity?

What is the slope of the velocity vs. time graph for the projectile motion?

What does the horizontal line in the projectile motion graph represent?

What are the components of the initial velocity vector for a football kicked at an angle of 30° with an initial velocity of 40 m/s?

A projectile is launched at 68.0° above the horizontal and at a speed of 55 m/s. What is the maximum height reached by the projectile?

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?

What happens to the range of a projectile when it is launched at a greater angle?

What equation(s) can you use to answer the question:

what is the maximum height that the ball reaches?

A projectile is launched from a height with an initial horizontal velocity of 20 m/s. If the projectile flies for 40 seconds, what is its horizontal velocity just before it hits the ground?

Suppose Lemming A runs off the edge of the cliff at 2 m/s and Lemming B runs off the edge at 1 m/s. Which will hit the ground farther from the base of the cliff?

What are the horizontal and vertical components of the initial velocity given the angle of 36 degrees?
