A bomb at rest explodes into three pieces of equal masses. If two pieces move perpendicular to each other, each with a speed v then the speed of the third piece is

Options

  1. AV
  2. Bv 2
  3. Cv 2
  4. D2 v

Correct answer

B. v 2

Step-by-step solution

Apply the conservation of momentum aligned & 3 m 0=m v ₁+m v ₂+m v ₃ & 0=m v i +m v j +m v ₃ & v ₃=-v i -v j & |v₃ |= (-v)^2+(-v)^2 = 2 v aligned
