# Projectile motion and kinematics in 2D

• Ajeezy
In summary, projectile motion is the motion of an object under the influence of gravity, following a curved path. The main difference between projectile motion and regular motion is the presence of gravity, which causes a curved path instead of a straight line. The formula for calculating the distance traveled by a projectile is d = v0t + 1/2at^2. The angle of projection affects the initial velocity and direction of the projectile, which in turn determines the shape and range of the trajectory. The horizontal and vertical components of projectile motion refer to the motion in the x-axis and y-axis respectively, with the horizontal component remaining constant and the vertical component being affected by gravity.

## Homework Statement

A dolphins leaps out of the water at an angle of 35 degrees above the horizontal. The horizontal component of the dolphin's vleocity is 7.7 m/s. Find the magnitude of the veritcle component.

## Homework Equations

I'm not sure what equations to use.

## The Attempt at a Solution

No attempts either, I'm totally clueless.

thanks for any help

How are the components of the velocity vector related to its magnitude?

you know the horizontal component, and you know that horizontal component*costhetheta yields an answer of 7.7 m/s , so find vi, and solve for vertical component

## What is projectile motion?

Projectile motion refers to the motion of an object that is moving through the air or space under the influence of gravity. It follows a curved path known as a parabola.

## What is the difference between projectile motion and regular motion?

The main difference between projectile motion and regular motion is that in projectile motion, the object is subject to the force of gravity in addition to any other forces acting on it. This causes the object to follow a curved path instead of a straight line.

## What is the formula for calculating the distance traveled by a projectile?

The formula for calculating the distance traveled by a projectile is d = v0t + 1/2at2, where d is the distance, v0 is the initial velocity, t is the time, and a is the acceleration due to gravity.

## How does the angle of projection affect the path of a projectile?

The angle of projection is one of the factors that determine the path of a projectile. The angle determines the initial velocity and direction of the projectile, which affects the shape and range of the trajectory.

## What is the difference between horizontal and vertical components of projectile motion?

The horizontal component of projectile motion refers to the motion of the object in the x-axis, while the vertical component refers to the motion in the y-axis. The horizontal component remains constant, while the vertical component is affected by the force of gravity.
