The value of theta is θ = 180° and 360° respectively.
Explanation:
Momentum = mass x velocity
P1 = mv
P2 = - mv
|P| = P1 - P2\
|P| = mv - (-mv)
|P| = 2mv ( Maximum momentum change)
|P| = P1 - P2
|P| = mv -mv = 0 (Minimum momentum change)
θ = 180° and 360°
So
the value of theta is θ = 180° and 360° respectively.
