A geocentric system is a part of the astronomical theory which describes the universe. Meaning that it puts the Earth in the CENTER of the universe as a point of view for other objects surrounding it.
Answer:
91.8 N
Explanation:
For the second law of Newton, the resultant force (F) is the mass(m) multiplied by the acceleration (a). Two forces are acting: the weight and the force exerted by the bungee cord (Fb). They are at same directions but in different ways, so the resultant force will be the difference between them (Fb is in a positive way):
Fb - m*g = m*a
The acceleration is on downward, so it is -8.3 m/s²
Fb - 54*10 = 54*(-8.3)
Fb = -448.2 + 540
Fb = 91.8 N
