Question

A massless rope of length 100 m and of breaking strength 108 N is hanging from the branch of a tree. A monkey of mass 6kg is trying to climb up the rope starting from rest. Find the shortest time in which monkey can climb the full length of rope with uniform acceleration so that the string will not break?

Options:

Answer:

C

Solution:

$T - m g = ma 108 - 60 = 6 a a = 8 m / s^{2} s = 0 + \frac{1}{2} a t^{2} 100 = \frac{1}{2} \times 8 \times t^{2}$
