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:
set(0, 'defaultAxesFontSize', 16) set(0,'defaultTextFontSize',14) set(0,'defaultLineLineWidth',3)
Commit the changes to your repository.
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. Create a function,
projectile.mthat 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.
>> 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.mto set the plot defaults before outputting the result.
