Two different unknown masses A and B collide. A is initially at rest when B has a speed v. After collision B has a speed v/2 and moves at right angles to its original direction of motion. Find the direction in which A moves after collision.

Two balls A and B having different but unknown masses, collide elastically. A is initially at rest when B has a speed v. After collisio B has a speed v/2 and moves at right angles to its original motion. (a) find the direction in which ball A moves after collision (b) Determine the speed of A.

Two spheres A and B of masses m_1 and m_2 respectively collide . A is at rest initially and B is moving with v velocity along x-axis . After collision B has a velocity v/2 in a direction perpendicular to the original direction . The mass A moves after collision in the direction.
