Tessellate - S.T.E.M.S - Physics - School - Set 2 - Problem 4

A military tank moves with velocity $V$ along x-axis and has its gun making angle $\theta$ with respect to x-axis. A bullet is shot is fired with velocity $'v'$ (with respect to tank).

$V = 10 m/s$ , $v=20 m/s$ , $\theta = 60^o$

mass of tank (without bullet) = 9 kg

mass of bullet = 1 kg

For a person on the ground, after the bullet is shot, the velocity vector of bullet makes an angle $'\phi'$ . What is the angle of the velocity vector with respect to x-axis?
