Physics - NLM Question with Solution | TestHub
Two persons of equal weight are hanging by their hands from the ends of a light rope hung over a frictionless pulley. They begin to climb the rope. One person can climb with twice the speed of the other (with respect to the rope). Who will get to the top first ?.
Options:
Answer:
Solution:
Since the weights of the two men are the same there will be no relative acceleration of either of
the men with respect to the other. Hence their relative velocity in the upward direction must remain
constant. Hence assuming that they both started to climb when they were at the same level i.e. face to
face to with each other, the twice-faster climber will effectively have twice as much length of rope to
climb as the other, because initial relative velocity being zero, it will continue to be so throughout. So the
two men will continue to climb remaining always face to face. Hence they will reach the pulley top
simultaneously.
