# Projectile Motion - one question.

In summary, projectile motion refers to the motion of an object thrown or projected into the air, influenced by gravity and resulting in a curved path. The factors that affect projectile motion include initial velocity, angle of projection, mass, air resistance, and gravity. It can be calculated using equations of motion and trigonometry. Horizontal motion is constant and unaffected by gravity, while vertical motion is influenced by gravity, resulting in a curved path. Projectile motion is used in various real-life applications such as sports, military and defense, engineering, and in understanding the motion of objects in the natural world.

## Homework Statement

You take a running jumpoffthe end of a diving platform at a speed of 7m/s and splash into the water 1.5 sconds later.

a. how far horizontally do you land from your takeoff point?
b.how high is the diving platform

## The Attempt at a Solution

a.)10.5m
b.)11.02m

right or wrong

X= Vot I get same answer 10.5

h = 1/2 gt^2 I get 11.03

Your calculations seem to be correct. In projectile motion, the horizontal distance traveled is determined by the initial velocity and time, while the vertical distance is determined by the acceleration due to gravity and time. Based on the given information, your answers for both a) and b) appear to be accurate. However, it would be helpful to show your work and equations used in your solution to ensure accuracy and understanding.

## 1. What is projectile motion?

Projectile motion refers to the motion of an object that is thrown or projected into the air, under the influence of gravity. It is a type of motion that combines both horizontal and vertical components, resulting in a curved path.

## 2. What are the factors that affect projectile motion?

The factors that affect projectile motion include the initial velocity, the angle of projection, the mass of the object, the air resistance, and the force of gravity. These factors determine the trajectory and range of the projectile.

## 3. How is projectile motion calculated?

Projectile motion can be calculated using the equations of motion and the principles of trigonometry. The initial velocity, angle of projection, and other factors are used to determine the horizontal and vertical components of the projectile's motion, which can then be used to calculate its trajectory and range.

## 4. What is the difference between horizontal and vertical motion in projectile motion?

In projectile motion, the horizontal motion is constant and unaffected by gravity, while the vertical motion is influenced by gravity and changes over time. This results in a curved path for the projectile, with the horizontal and vertical components combining to form the overall trajectory.

## 5. How is projectile motion used in real life?

Projectile motion is used in various real-life applications, such as sports (e.g. throwing a ball), military and defense (e.g. launching missiles), and engineering (e.g. designing bridges or projectiles). It is also a fundamental concept in physics and is used to understand the motion of objects in the natural world.
