# Moving a 250kg Elephant with 425N Force

• physicshard22
In summary, the conversation discusses the concept of moving a 250kg elephant with 425N of force. It is important to use the correct amount of force to ensure the safety of the elephant. Other factors, such as friction and weight distribution, also play a role in the success of moving the animal. Moving an elephant with only 425N of force is unlikely and it is more feasible to use a team of people or mechanical devices. The amount of force needed to move an elephant can be calculated by considering the weight of the elephant, desired acceleration, and mechanical advantage.

## Homework Statement

A boy puts a 250kg elephant on a piece of carpeting and slides it across the floor by exerting a horizontal force of 425N on the elephant

Ff = uKFn

## The Attempt at a Solution

Fn = Fg
Fnet = Fap - Ff
Fnet = 425 - Ff
ma = 425 - uKFn
250a = 425 - uK(2450)

for coefficient of kinetic friction

mue=f max/fn
425N/(250x9.81)
mue=.173

I believe that's how you do it

why is friction 425N

its force

## 1. How can a 250kg elephant be moved with only 425N of force?

The key to moving a heavy object like an elephant with a relatively small amount of force is to use a mechanical advantage. This can be achieved by using tools such as pulleys, levers, or inclined planes to amplify the force applied.

## 2. Why is it important to use the correct amount of force when moving an elephant?

Using too much force can potentially harm the elephant, while using too little force may not be effective in moving the animal. It is important to carefully calculate and apply the appropriate amount of force to ensure the safety and well-being of the elephant.

## 3. What other factors besides force are important when moving an elephant?

In addition to force, other factors such as friction, weight distribution, and the surface on which the elephant is being moved can also affect the ease and success of the task. It is important to consider all of these factors when planning to move an elephant.

## 4. Can an elephant be moved by one person with 425N of force?

It is unlikely that one person would be able to move a 250kg elephant with only 425N of force, as it would require a significant amount of strength and leverage. It is more feasible to use a team of people or mechanical devices to move an elephant safely and effectively.

## 5. How can the amount of force needed to move an elephant be calculated?

The amount of force needed to move an elephant can be calculated by considering the weight of the elephant, the desired acceleration or speed of movement, and the mechanical advantage being used. This can be determined through mathematical equations or by consulting with experts in the field of mechanics and animal handling.
