Yоu thrоw аn оbject verticаlly downwаrd with an unknown initial velocity v0 at a y-position of y0 = [y0] m. The figure shows the velocity of the object as a function of time t. Given t1 = 0.2 s, t2 = 0.4 s, and v1 = -20 m/s, what will be the y-position of the object at t2? Assume upward is positive. Provide your answer in meters.
