Calculate the air jet flow velocity with the nozzle area of $2$ $cm^2$, if it has to move a $0.5$ $kg$ block on a surface with coefficient of friction $0.34$. Assume that the jet strikes the block perpendicular to its side and the density of air is $1.2$ $kg/m^3$.

A. 1.7 m/s
B. 3.4 m/s
C. 72 m/s
D. 83 m/s
E. 119 m/s
