A shell acquires the initial velocity v = 320m/s, having made n = 2.0 turns inside the barrel whose length is equal to l = 2.0m. 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.

2. Relevant equations

vf = vi + at

This equation can be used for linear as well as angular velocity

x = vit + at^2

vf^2 - vi^2 = 2ax

3. The attempt at a solution

The given answer is 2pi nv/l = 2.0 x 10^{3}rad./s
