A monkey of mass 40 kg climbs on a rope. which can stand a maximum tension of 600 N. In which of the following cases will the rope break: the monkey (a) climbs up with an acceleration of `6 m s^(-2)` (b) climbs down with an acceleration of `4 m s^(-2 )` (c) climbs up with a uniform speed of `5 m s^(-1)` (d) falls down the rope nearly freely under gravity? (Ignore the mass of the rope).

Explanation

(a) T – 400 = 240, T = 640 N (b) 400 – T = 160, T = 240 N ( c) T = 400 N (d) T = 0
The rope will break in case (a).
