Physics - NLM Question with Solution | TestHub

assume block of mass $100 \mathrm{kg}$ is moving upward with acceleration $a$ with respect to ground and tension in the rope is $T$. Then,

for man 

$T-60g=60\left(\frac{5g}{4}-a\right)$  .......$\left(1\right)$  ( $\because$ man is climbing on the rope with acceleration $\frac{5g}{4}$ )

for block

$T-100g=100a$ ......$\left(2\right)$

solving equation $\left(1\right)$ and $\left(2\right)$

$T=1218.7 \mathrm{N} \approx 1218 \mathrm{N}$
