A hot-air balloonist, rising vertically with a constant velocity of magnitude v = 5.00 m/s, releases a sandbag Part H at an instant when the balloon is a height h = 40.0 m above the ground (Figure 1). After it is released, the sandbag is in free fall. For the questions that follow, take With what magnitude of velocity does it strike? the origin of the coordinate system used for measuring displacements to be at the ground, and upward Express your answer in meters per second. displacements to be positive.
