How to solve...

At time, $t=0,$ a golf cart is at $x=0$ with acceleration described by the graph below. Sketch a separate graph of the velocity versus time. Use the area under the $v(t)$ curve to determine the final location, $x_f,$ of the golf cart. Show any work. Give all rationale. If you use an equation, write it first, and put units on any numbers that require units.
