Question

two objects a and b move toward each other with speeds of 10 m/s and 2 m/s, respectively. the mass of a is 2 kg and that of b is 10 kg. after a head-on, perfectly inelastic collision, the speed of a and b is? g

Answer 1

Answer:

The speed of a and b will be same about 3.333 m/s after collision.

Explanation:

In a perfectly inelastic collision the bodies gets attached to each other after collision .

In this type of collision the final  kinetic energy gets lowered than the initial one. Whereas the momentum before and after the collision still remains constant.

Thus we apply the theory of conservation of momentum.

M1V1+ M2V2 = (M1+M2)V

Thus V= 40/12 =3.33 m/s
