A shell acquires the initial velocity \( 320 \mathrm{~m} / \mathrm{s} \), having turned
\( \mathrm{P} \) complete two revolutions inside the barrel whose length is equal

W to \( 2 \mathrm{~m} \). Assuming that the shell moves inside the barrel with uniform acceleration, find the angular velocity of its axial rotation at the moment when the shell escapes the barrel.
