1)a bullet of mass 10kg is horizontally fired with a velocity 100mps from a gun of mass 10kg the gun will move backward with linear momentum
..
2) two objects of masses 10kg and 15kg are moving in the same direction with different velocities 5m/min and 10m/min respectively . if they collide and stick together and move with common velocity then the magnitude of their common velocity
(Do u think physics is Easy ??? If yes why u are not able to answer this??)(please any experts answer my question)
