a 13 kg mass traveling at 4 m/s meets and collided with a 3 kg mass traveling at 6 m/s in the opposite direction. the object bounce off of each other. take the rightward direction to be positive name the type of collision. then find the final velocities of both objects

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.

Ithink the answer is d

The best answer i can think of is b
