# Projectile Launcher

This is the page for Frances Hunter's final project.

## Contents

## Motivation

To apply the concepts of projectile motion to a practical situation. Also, it seemed like a cool idea.

## Design

The main component of my project is a projectile launcher attached to a servo. The launcher is powered by a spring (compressed to the same distance each time to produce a consistent initial velocity) and loaded with a small metal ball. The servo is connected to a Matlab program which, given the range from the target, turns the launcher to the correct angle. With no variation in initial velocity, the range will be dependent on the launch angle. The spring is then released by hand.

## Data

## Materials

- Servo with connecting cords

- Matlab

- Spring, plug, and loading rod

- Nail

- Plastic tubing

- Metal ball

- Assorted screws, string, and double-sided tape

- Target

## Timeline

Week of 11/17: Collect materials; plan exact design; solve physics that will underlie the Matlab program.

Week of 11/24: Construct launcher and determine initial velocity; write Matlab code.

Week of 12/1: Mount launcher on the servo and frame; debug.
