\textbf{159.} Two balls A and B are thrown from height $h$ at the same time from the same point, with speeds $V_A = 32\ \dfrac{\text{m}}{\text{s}}$ and $V_B = 22\ \dfrac{\text{m}}{\text{s}}$, both thrown vertically upward. At the moment ball B reaches its highest point, what is the distance between the two balls?
(Air resistance is neglected. $g = 10\ \dfrac{\text{m}}{\text{s}^2}$.)
