Question

A shell of mass M is moving with a velocity V. it explodes into two parts, and one of the parts of mass m is left stationary. What will be the velocity of the other part.

(A) MV/ (M - m)

(B) MV/ ( M + m)

(C) mV/ (M - m)

(D) mV/ (M + m)

Answer 1

Answer is (A) MV/ (M - m)

Apply conservation of momentum MV = (M - m)ν.
