A 1.0 Kg object, A, with a velocity of 4.0m/s to the right, strikes a second object, B, of mass 3.0Kg, originally at rest. In the collision, A is deflected from its original direction through an angle of 50 degrees; its speed after the collision is 2.0m/s. Find the angle between B's velocity after the collision and the original direction of A, and find the speed of B after collision. pdf
