The velocity v(t) of some particle is plotted

as a function of time on the graph below. The

scale on the horizontal axis is 1 s per division

and on the vertical axis 9 m/s per division.

Initially, the particle is at x0 = 52 m. What is the position x of the particle at

time t = 4 s?

Answer in units of m
