A ball of mass M = 1.5 kg, suspended on an inextensible thread of length l = 55 cm, is hit and stuck by a bullet of mass m = 10 g. The bullet flies obliquely from top to bottom at an angle a = 30° to the horizon (Fig. ). Bullet speed v = 400 m/s. At what angle φ will the ball with the bullet deviate?
