As a runaway scientific balloon ascends at 19.6 m/s, one

As a runaway scientific balloon ascends at 19.6 m/s, one of its instrument packages breaks free of a harness and o free-falls. Figure 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 is the break-free point above theground?
