A 10 $\mathrm{kg}$ monkey climbs up a massless rope that runs over a
frictionless tree limb and back
down to a 15 $\mathrm{kg}$ package on the
ground (Fig. $5-54 )$ . (a) What is the
magnitude of the least acceleration
the monkey must have if it is to lift
the package off the ground? If, after the package has been lifted, the
monkey stops its climb and holds
onto the rope, what are the (b)
magnitude and (c) direction of the
monkey's acceleration and (d) the
tension in the rope?
