A spherical mass (m1 at 4 kilograms), moving at 10m/s from the northwest (or from the direction of 315 degrees), collides with another spherical mass (m2 at 2 kilograms), moving at 5m/s from the south (or from the direction of 180 degrees). Mass m2 is now redirected toward the southwest (or towards the direction of 225 degress). How would one calculate for the new direction of m1? Thank you. P.S.: Not homework.
