Consider a body shown in the figure, consisting of two identical balls, each of mass M connected by a light right rod. If an impulse J=M V ( V= linear velocity of ball)is imparted to the body at one of its ends, what would be its angular velocity?

Options

  1. AV 3 L
  2. BV 4 L
  3. CV L
  4. D2 V L

Correct answer

C. V L

Step-by-step solution

Impulse J= P aligned & M V=2 M v^ -0 & v^ = V 2 aligned The rod will rotate about its COM. Thus, v^ = R= ( L 2 ) = 2 v^ L = V L
