Ball A of mass m= 1 kg is projected from a spring activated gun as shown below. the spring has a constant of k = 500N/m. when the spring is fully compressed 0.2 m. assume frictionless barrel.while fully compressed the spring is released. as the ball leaves the barell it slides no rolling on a smooth surface for 500mm and then it collides with ball B of the same mass in a perfect elastic collision. a) what is the speed of ball A before the impact? b) what is the motion of balls A and B after the impact?
