A monkey of mass 15 kg is climbing on a rope with one end fixed to the ceiling. If it wishes to go up with an acceleration $1 \mathrm{~m} / \mathrm{s}^2$, how much force should it apply to the rope if rope is 5 m long and the monkey starts from rest?

The correct answer is:
165 N
The mass of monkey $=15 \mathrm{~kg}$
$a=1 \mathrm{~m} / \mathrm{s}^2$
For the motion of the monkey $T-[15 g-15(1)]=0$ Hence, $T$ is tension in the string $T=15 g+15$
$\begin{aligned} T & =15(10+1)=15 \times 11 \\ & =165 \mathrm{~N}\end{aligned}$
$a=1 \mathrm{~m} / \mathrm{s}^2$
