Answer :
The inertia of the elephant Mel in terms of the inertia Mm of the monkey is 2Mm
the moment = 0
from monkey & giraffe
Mm*3d = Mg*d
Mg = 3*Mm
-------------------
for Me & Mg
(Mg + Mm)*2d = Me*4d
(3Mm+Mm)*2d = Me*4d
4*Mm*2 = 4*Me
Me = 2Mm
Until some force changes the speed or direction of an object, it will continue to move in the same direction. This is known as inertia. The phrase is correctly understood as a shortened form of "the principle of inertia," which is a concept that Newton discussed in his first law of motion. Unless influenced by an unbalanced force, an object at rest stays at rest, and an object in motion stays in motion while maintaining a constant speed and a straight line. An object at rest has a tendency to stay at rest, and an object in motion has a tendency to continue moving in a straight line at a constant speed.
