Question

Two equal masses each of mass M are joined by a massless rod of length L. Now an impulse MV is given to the mass M making an angle of 30° with the length of the rod. The angular veloctiy of the rod just after imparting the impulse is

  1. fraction numerator v over denominator L end fraction    
  2. fraction numerator 2 v over denominator L end fraction    
  3. fraction numerator V over denominator 2 L end fraction    
  4. none of these.    

The correct answer is: fraction numerator 2 v over denominator L end fraction

One ice skater of mass m moves with speed 2v to the right, while another of the same mass m moves with speed v toward the left, as shown in figure I. Their paths are separated by a distance b. At t = 0, when they are both at x = 0, they grasp a pole of length b and negligible mass. For t > 0, consider the system as a rigid body of two masses m separated by distance b, as shown in figure II. Which of the following is the correct formula for the motion after t = 0 of the skater initially at y = b/2?
