A projectile of mass \( m \) is fired with a velocity \( v \) from point \( P \) at an angle \( 45^{\circ} \). Neglecting air
\( \mathrm{P} \)
resistance, the magnitude of the change in momentum leaving the point \( P \) and arriving at \( Q \) is
(1) \( \sqrt{2} m v \)
(2) \( 2 m v \)
(3) \( \frac{m v}{2} \)
(4) \( \frac{m v}{\sqrt{2}} \)
