Question

In the figure given below, the end B of the rod AB which makes angle  with the floor is pulled with a constant velocity v0 as shown. The length of rod is . At an instant when = 37º

  1. Velocity of end A is fraction numerator 4 v subscript 0 end subscript over denominator 3 end fraction  
  2. angular velocity of rod is fraction numerator 5 v subscript 0 end subscript over denominator 6 l end fraction  
  3. angular velocity of rod is constant  
  4. velocity of end A is constant  

The correct answer is: Velocity of end A is fraction numerator 4 v subscript 0 end subscript over denominator 3 end fraction
