How far will the football travel before it lands? Round your answer to the nearest tenth. 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 do you calculate how far a ball will travel before it hits the ground?

The equation for the distance traveled by a projectile being affected by gravity is sin(2θ)v2/g, where θ is the angle, v is the initial velocity and g is acceleration due to gravity.

## How long is the ball in flight before striking the ground?

It takes about 88 seconds for the cannonball to reach its maximum height (ignoring air resistance). You have 176 seconds, or 2 minutes and 56 seconds, until the cannonball destroys the cannon that fired it.

## How do you determine where a ball will land?

Both balls will take 2 seconds to hit the ground.

The red ball is traveling at 35 m/s at the release. It travels in the air for 2 seconds. Using the equation, d = vt for linear motion, The distance traveled in air is 35 m/s x 2 seconds = 70 meters. The red ball will land 70 meters from the base of the cliff.

## How far did the ball travel horizontally before striking the ground?

You can therefore conclude that the baseball travels 26.8 meters horizontally before reaching the ground.

## How high above the ground does the ball go?

Problem Answer:

The ball go above the ground as high as 11.30 m.

## What makes the ball stop rolling at the same time?

When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because of friction.

## How can you tell how long a ball is in the air?

Use the vertical motion model, h = -16t2 + vt + s where v is the initial velocity in feet/second and s is the height in feet to calculate how long the basketball will be in the air for.

## What is the acceleration of the ball just before it hits the ground?

So the acceleration of the projectile is equal to the acceleration due to gravity, 9.81 meters/second/second, from just after its thrown, through its highest point, and until just before it hits the ground.

## How do you calculate flight time?

The time of flight of an object, given the initial launch angle and initial velocity is found with: T=2visinθg T = 2 v i sin .

## Will the ball move by itself?

1 Answer. Nothing is stored, actually. Here, on Earth we are used to the fact that things “naturally” stop moving after a while (if we do not make them continue the movement somehow) “by themselves”. … However, if there is no force opposing the movement (which we never experience on Earth) the ball will just keep moving.

## What is the only force acting on the projectile?

A projectile is an object upon which the only force is gravity. Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity.

## What factors affect how far a projectile will land?

Factors affecting the flight path of a Projectile are:

- Gravity.
- Air Resistance.
- Speed of Release.
- Angle of Release.
- Height of Release.
- Spin.

## Which projectile traveled the greatest horizontal distance?

This is because the vertical motion determines the time in the air. At 45° the venical and horizontal motions are bulanced The angle that results in maximum range (dx) is 45°, 45 degrees or the angle closest to 45 will result in the greatest horizontal distance traveled.

## When a ball is thrown horizontally and another is dropped which will hit the ground first?

If the ball is thrown exactly horizontally, then it will hit the ground at the same time as the dropped one – but it will a lot further away from the thrower.

## What is the 1st step when solving projectile motion problems?

Make a clearly labelled sketch of the projectile motion. If you are given the initial velocity, resolve it into its x and y components. Analyze the horizontal and vertical motion separately. Decide on your sign convention.
