1.	Two solid balls of rubber A and B whose masses are200 gm and 400 gm respectively, are moving inmutually opposite directions. If the velocity of ballAis 0.3 m/s and both the balls come to rest aftercollision, then the velocity of ball B is(1) 0.15 m/s(2)-0.15 m/s(3) 1.5 m/s(4) of the above
Answer» Let after collision the velocity of ball B is "V" as they both have come to rest after collision Their momentum will be equal so M1V1= M2V2 0.2×0.3 = 0.4×V2....(converted mass into kg) Then by solving we will get V2 which is velocity of ball b is 0.15sec

Answer»

Let after collision the velocity of ball B is "V" as they both have come to rest after collision

Their momentum will be equal so M1V1= M2V2

0.2×0.3 = 0.4×V2....(converted mass into kg)

Then by solving we will get V2 which is velocity of ball b is 0.15sec
