As a runaway scientific balloon ascends at $19.6 \mathrm{~m} / \mathrm{s}$. one of its instrument packages breaks free of a harness and free-falls. Figure $2-37$ gives the vertical velocity of the package versus time, from before it breaks free to when it reaches the ground. (a) What maximum height above the break-free point does it rise? (b) How high was the break-free point above the ground?
