3. A person lifts himself up by hand using the pulley system shown below. “Assume
the total mass of the person and the swing stage is m and the masses of the pulley and
the rope are negligible.。Also, assume there is no frictional force between the pulley
and the rope.(a) What 1s the minimum force, Fmim, applied by the person's left hand
to the rope so that he does not fall down? The person moves up when the applied
force Fis larger than Fmin. “Then, for this F find (b) the acceleration of the person
and (c) the tension in the rope. (d) How much work is done by the person/person's
hand ifthe person goes up, say, by a distance“h””?
