Two skaters collide and embrace, in a completely in elastic collision. That is they stick together after impact, as suggested by figure, where the origin is placed at the point of collision. Alfred, whose mass mA is 83 kg, is originally moving east with speed nA = 6.2 km/h. Barbara, whose mass mB is 55 kg is originally moving north with speed nB = 7.8 km/h.

What is the velocity (km/hr) v of the couple after impact?
    Correct answer is '4.9'. Can you explain this answer?

    Linear momentum is conserved during the collision. We can write, for the linear momentum components in the x and y directions,

    in which M = mA + mB. Dividing equation (2) by equation (1) yields

    Thus

    From equation (2) we then have
