Apparent Weight & Lift

A monkey of mass 20 kg is holding a vertical rope. The rope will not break when a mass of 25 kg is suspended from it but will break if the mass exceeds 25 kg. What is the maximum acceleration with which the monkey can climb up along the rope? (g = 10 m/s2)

Show answer and solution

Answer: (d)

Maximum tension $T = 25 \times 10 = 250$ N.
Climbing up: $T - mg = ma \Rightarrow 250 - 200 = 20a$
$a = 2.5\text{ m/s}^2$
So the answer is (d) 2.5 m/s $^2$ .
