A monkey of mass 50 kg climbs on a rope which can withstand the tension (T) of 350 N. If monkey initially climbs down with an acceleration of 4 m/s² then climbs up with an acceleration of 5 m/s². Choose the correct (g = 10 m/s²).

1. T = 700 N while climbing upward
2. T = 350 N while going downward
3. Rope will break while climbing upward
4. Rope will break while going downward

Correct answer: Rope will break while climbing upward

Solution

When the monkey climbs upward with an acceleration of 5 m/s², the tension in the rope increases due to both the weight of the monkey and the additional force from the upward acceleration, resulting in a total tension of 700 N, which exceeds the rope's maximum capacity of 350 N, causing it to break.
