Question

A monkey of mass 40 kg climbs up a rope, of breaking load 600 N hanging from a ceiling. If it climbs up the rope with the maximum possible acceleration, then the time taken by monkey to climb up is [ Length of rope is 10 m ]

1. 2s      2. 1s      3. 4s

Read 2 Solution.

breaking load = tension in string=600N

in balance condition

T -- mg = ma

600 - 40X10 = 40 a   => a = 200/40

a=5 ms-2      Now use s= ut + 1/2at2   u=0 there4   s= 1/2at2  [  length=s=10m}  thus , t2=( 10X2 ) /5  on solving t= 2s  (1 optn)
