Use the concept of impulse to explain the difference in the results of a jump using a proper bungee cord and a jump using ordinary rope.
(Ans: Is it that impulse is equal to mVf - mVi and the final velocity will be zero for the ordinary rope, however when using the bungee cord it is elastic, it prolongs the time it takes to reach the final velocity of zero hence making it safe for the bungee jumper. )
Is that correct?
