# Homework #2
## due 2/3/17

1. Now that you have created your own repository, 'homework_1', that has a README.md file.
Create a new file in this repository called `setdefaults.m`. This file is a matlab/octave
script that will set default plotting parameters. In this file, add the following lines:

```matlab
set(0, 'defaultAxesFontSize', 16)
set(0,'defaultTextFontSize',14)
set(0,'defaultLineLineWidth',3)
```

Commit the changes to your repository.

![projectile(v_mag,theta) predicts the height of the projectile based upon initial
velocity and position, as see in the Figure](projectile.png)

2. Clone your 'homework_1' repository to your own computer. Now, we want to create a
function that uses kinematic formulas to predict the path of a projectile. The dimensions
are taken from official dart board dimensions
[darts](http://dartbrokers.com/dartboard-height.html). Create a function,
`projectile.m` that will calculate the location of an object with an initial velocity. The
function inputs are v_mag (initial speed), theta (initial angle). The output is the height
of the object 2.37 m from its starting position. Assume g=9.81 m/s^2 and its initial
height is 1.72 m.

```matlab
>> h=projectile(v_mag,theta)

h= 1
```

In addition to the output of `h`-height at 2.37 m-plot the path of the object from its
initial position to its position at 2.37 m away from the start. *Note: use your
`setdefaults.m` to set the plot defaults before outputting the result.*
