A monkey is at rest on a weightless rope which goes over a pulley and
is tied to a bunch of bananas at the other end. The weight of the
bunch of bananas is exactly the same as that of the monkey. The
pulley is frictionless and weightless. The monkey starts to climb up the
rope to reach the bananas. As he climbs, the distance between him
and the bananas will
