Write a Matlab function M$-$file to compute v as a function of t$.$ Name it as

$$velocity$.$m$.$

$(2)$ Write a Matlab script M$-$file to generate a table of v versus t for t$=-10$ to $60$ at

increments of $0\mathrm{.}5,$ and a plot according to the table. $($You may call the function in

problem $(1)$ in your script$).$

$(3)$ Draw your plot according to what you got from running your script in Matlab.
