Two objects, one of mass 3 kg and moving with speed of 2 m/s and the other of mass 5 kg and speed 2 m/s, move toward each other and collide head-on. If the collision is perfectly inelastic, find the speed of the object after the collision. |

Answer» 0.25m/s `m_(1)v_(1)+m_(2)v_(2)=(m_(1)+m_(2))v'` `v'=(m_(1)v_(1)+m_(2)v_(2))/(m_(1)+m_(2))` `=((3KG)(2m//s)+(5kg)(-2m//s))/(3kg+5kg)` `=-0.5m//s`. |
