Answer:
0.64 m
Explanation:
The first thing is calculate the center of mass of the system.
now multiplying every coordinate x by the mass of each object (romeo, juliet and the boat) and dividing all by the total mass taking by reference the position of juliet.
X_cm = 1.4589 m
When the forces involved are internals, the center of mass don't change
After the movement the center of mass remains in the same distance from the shore, but change relative to the rear of the boat.
X_cm= 2.10 m
this displacement is how the boat move toward the shore.
2.10-1.46= 0.64 m

Explanation:
The Second or the Entropy law of thermodynamics states that every time energy is transformed from one form to another, some of that energy is converted to heat. That means there is never 100% conversion of one form of usable energy to another. Because Heat is not available to do work , the usable amount of energy is wasted each time an energy conversion occurs.
