T'S GIVEN THAT THE PERCENTAGE ERROR IN MOMENTUM MEASUREMENT AS 100%, the question is the percentage error in kinetic energy, answer:  if % error is more than 5-6% ,the error analysis can't be applied and we have to apply conventional method. so ur answer is right as it is not 200% but 300% will be the increase in k.e.
