Question 8 (1 point) Two objects of mass 7.20 kg and 6.90 kg collide head-on in a perfectly elastic collision. If the initial velocities of the objects are respectively 3.60 m/s [N] and 13.0 m/s [S], what is the velocity of both objects after the collision? O 8.20 m/s [S]; 0.353 m/s [N] O 0.30 m/s [S]; 17.0 m/s [N] O 12.6 mfs [S]; 3.95 m/s [N] O 16 m/s [N];0m/s
