Billiard ball A of mass m_A = 0.130 kg moving with speed v_A = 2.50 m/s strikes ball B, initially at rest, of mass m_B = 0.145 kg. As a result of the collision, ball A is deflected off at an angle of 31.0 degree, with a speed v_A1 = 2.05 m/s.

Write down the equation expressing the conservation of momentum for the components in the y direction.

Express your answer using the variables (mA, mB, VA, VA1, θA, θB)

answer should be, 0=(equation with variables)
