Q. A man wants to slide down a rope. The breaking load for the rope $\frac{2}{3}$ rd of the weight of the man. With what minimum acceleration should fireman slide down?
A) $\frac{g}{4}$
B) $\frac{g}{3}$
C) $\frac{2g}{3}$
D) $\frac{g}{6}$
Explanation
(b) Tension is rope, $T <$ Breaking load, $\frac{2}{3}mg$
$\therefore m(g - a) < \frac{2}{3}mg$ or $a > \frac{g}{3}$
