A monkey of mass 40 kg climbs on a rope which can stand a maximum tension 600 N. In which of the following cases will the rope break? The monkey (a) climbs up with an acceleration of 6m/`s^2` (b) climbs down with an acceleration of 4m/`s^2` (c) climbs up with a uniform seed of 5m/s (d) falls down the rope freely under gravity. Take g = 10m/`s^2` and ignore the mass of the rope.
