Two objects, one with a mass of 2.0 kg and the other with a mass of 3.0 kg, are approaching each other equally and with a speed of 5.0 m/s. Objects collide and become one piece.\ 1)Find the final velocity of the particles. 2)Find the amount of kinetic energy lost during the collision. 3)Assuming that the bodies approach each other at an angle of 90° before the collision (ie along the x and y axes), what will be the kinetic energy loss?
