Answer 1

v_b = velocity at the bottom of the window = (L_w/t) + (gt/2)

v_g = velocity just before hitting the ground = ?

a = acceleration = g

$\Delta$y = displacement from the bottom of the window to the ground = h_b

using the kinematics equation

v²_g = v²_b + 2 a $\Delta$y

v²_g = ((L_w/t) + (gt/2))² + 2 g h_b

v_g = sqrt(((L_w/t) + (gt/2))² + 2 g h_b)
