Question

A heavy but uniform rope of length L is suspended from a ceiling If the rope is given a sudden sideways jerk at the bottom, how long will it take for the pulse to reach the ceiling?

  1. square root of fraction numerator 2 L over denominator g end fraction end root    
  2. square root of fraction numerator L over denominator 2 g end fraction end root    
  3. fraction numerator 1 over denominator 2 end fraction square root of fraction numerator L over denominator g end fraction end root    
  4. root index 2 of fraction numerator L over denominator g end fraction end root    

The correct answer is: square root of fraction numerator L over denominator 2 g end fraction end root
