A fireman of mass 80 kg slides down a pole during a rescue mission. The force of friction is constant at 720 N. Find the acceleration of the man.

Q. A fireman of mass 60 kg slides down a pole. He is pressing the pole with a force of 600 N. The coefficient of friction between the hands and the pole is 0.5, with what acceleration will the fireman slide down ($g=10m/s^2$)

Q. A fireman of mass $60kg$ slides down a pole. He is pressing the pole with a force of $600N$. The coefficient of friction between the hands and the pole is $0.5$, with what acceleration will the fireman slide down $(g=10m/s^2)$

Q. A man slides down on a telegraphic pole with an acceleration $a=g/4$. The frictional force between the man and the pole is equal to (in terms of man's weight $W$)

Q. A fireman wants to slide down a rope. The rope can bear a tension $\frac{3}{4}th$ of the weight of the man. With what minimum acceleration should the fireman slide down :

Q.

A boy of mass m is sliding down a vertical pole by pressing it with a horizontal force $f$. If $\mu$ is the coefficient of friction between his palms and the pole, the acceleration with which he slides down will be equal to
