1.	A 16g mass moving in the +x direction at 30cm/s while a 4g mass is moving in the -x direction at 50cm/s . They collide head on and stick together find thier velocity after collision
Answer» APPLY conservation of momentum take +x direction as +ve then INITIAL momentum= final momentum. 16(30)+4(-50)=20(v)so v=280/20=14 cm/s .
