A man getting down a running bus, fallsforward because-a)Due to inertia of rest, road is left behind and man reaches forwardb)Due to inertia of motion upper part of body continues to be in motion in forward direction while feet come to rest as soon as they touch the roadc)He leans forward as a matter of habbitd)Of the combined effect of all the three factors stated in (A), (B) and (C)Correct answer is option 'B'. Can you explain this answer?

Question

Answer

The explanation is the question itself. Inertia is a property of which it resists its change of state of rest or state of motion, so as soon as the person jumps the lower part immediately comes to rest by sharing contact with the ground the upper body due to inertia of motion resists its change in state of motion.

Answer

Inertia of Motion and Rest
When a moving object comes to a sudden stop, the upper part of the object tends to keep moving due to its inertia of motion, while the lower part comes to rest. This principle can be applied to explain why a man falls forward when getting down a running bus.

Inertia of Motion
When the bus is in motion, the man inside the bus is also in motion. As the man prepares to get down, he starts to slow down his forward motion. However, the upper part of his body, which has more mass and therefore more inertia, tends to continue moving forward due to its inertia of motion.

Feet Come to Rest
As the man's feet touch the road, they come to a sudden stop. This is because the road provides a frictional force that opposes the motion of the man's feet. The friction between the man's feet and the road causes them to stop moving forward.

Upper Body Continues Forward
While the man's feet come to rest, the upper part of his body continues moving forward due to its inertia of motion. This results in the man falling forward as his upper body moves ahead while his feet remain stationary.

Leaning Forward Habit
It is also mentioned in the options that the man leans forward as a matter of habit. This habit of leaning forward while getting down a moving vehicle can contribute to the man falling forward. When the man leans forward, it shifts his center of gravity towards the front, making it easier for him to lose balance and fall forward.

Combined Effect of Factors
The correct answer states that the man falls forward due to the combined effect of all the factors mentioned in options A, B, and C. The inertia of motion of the upper body, the feet coming to rest, and the habit of leaning forward all contribute to the man falling forward when getting down a running bus.
