An 80-kg clown sits on a 20-kg bike on a tightrope attached between two trees. The center of mass of the clown is 1.6 mabove the rope, and the center of mass of the bike is 0.70 mabove the rope.
A load of what mass should be fixed onto the bike and hang 1.50 m below the rope so that the center of mass of the clown-bike-load system is 0.50 m below the rope? What is the force that the rope exerts on each tree if the angle between the rope and the horizontal is 14 ∘?

Two masses, m and M, of 1.0 and 3.0 kg, respectively, are
connected by rope passing through a pulley. The mass m is on an
inclined plane without friction making an angle 30o with the
horizontal. The mass M is on a horizontal plane without friction.
The pulley, located between the two masses, is of negligible mass
and offers no friction for the rope. A force, Fapp, is
applied to the mass M, as illustrated below.
