A body of mass M moving with velocity V explodes into two equal parts. If one comes to rest and the other body moves with velocity v , what would be the value of v ?

Options

  1. AV
  2. BV / 2
  3. C4 V
  4. D2 ~V .

Correct answer

D. 2 ~V .

Step-by-step solution

Before explosion, the total momentum of the system =M V After explosion, the total momentum of the system = M 2 0+ M 2 v= M v 2 From the principal of momentum conservation, aligned & M V= M v 2 & v=2 V aligned
