If I have initial position and velocity equations with unit vectors $($like r$1$: $3$x$^$ and v$1$: $0\mathrm{.}3$x$^+0\mathrm{.}2$y$^)$ I want to write a MATLAB code to plot the objects position over time t but Im not sure of the best way to do it because of the x and y in each position and velocity equation. Can you provide an example code for me to understand?
