While doing his physics homework, a student spontaneously decides to throw his laptop out the window. After it broke through the window pane, it had an initial velocity of approximately zero. If it subsequently experienced a constant acceleration of 9.81 m/s2 toward the Earth's center, what is the laptop's speed when it hits the ground 19 meters below?
