If an elephant were chasing you, its enormous mass would be very threatening. But if you zigzagged, the elephant’s mass would be to your advantage. Why?
The reason that it is difficult for elephant to have zigzagged motion.
Answer to Problem 38A
As an elephant has more mass and thereby more inertia, it is difficult for it to change its state of rest or motion.
Explanation of Solution
Introduction:
The more the mass of an object, the more will be its inertia and then more force will be needed to change its state of rest or motion.
Now, when the elephant moves straight then no force will be needed to change its motion, but when it tries to move zigzag, then more force will be needed to change its direction of motion due to more mass or greater inertia.
Conclusion:
Hence, it is difficult for elephant to move in a zigzag motion due to more mass and thereby due to more inertia.
