MatLab help

An object is fired straight up from the earth's surface at 200 feet per second. Its height s off the ground at time t is given by the function s(t)=-16t^2 + 200t.

Using MATLAB Vectorize s(t), v(t), and a(t) on this domain using increments of your choosing

Using MATLAB Graph the three functions s(t), v(t), and a(t) on the same graph.

Using MATLAB What are the velocity and acceleration at the time the object hits the ground? Use the subs command
