A 0.25-kg object (m1) is slid on a frictionless surface into a dark room, where it strikes an initially stationary object with mass of 0.4 kg (m2) . The 0.25-kg object emerges from thw room at an angle of 45° with its incoming direction. The speed of 0.25 kg object is originally 2 m/s and 1.5 m/s after the collision. Calculate the magnitude and direction of the velocity of the 0.4-kg object after the collision.
