An isolated 3 kg object is moving in the positive y direction along the -y axis at 2 m/s; when it reaches the origin it breaks into two pieces sending a 1 kg fragment in the +y direction at a speed of 3.7 m/s. what are the velocity and direction of the other piece immediately after the "explosion"?
