Question

obtain an express of momentum oftwo bodies of two bodies of mass M
1 and M2 having velocity v1 and v2 after collision they moves with a common velocity ..​

Answer 1

Answer:

Let two bodies of masses m

1

and m

2

moving with velocities u

1

and u

2

along the same straight line.

And consider the two bodies collide and after collision v

1

and v

2

be the velocities of two masses.

Before collision

Momentum of mass m
