# Force Required to Move a 25kg Block

## What is the force required to move a 25kg block along a horizontal floor?

Calculate the force needed to move the block with a coefficient of sliding friction of 0.19.

## Answer:

The force required to move a 25kg block along a horizontal floor with a coefficient of sliding friction of 0.19 is 46.05 N.

## Explanation:

The force required to move a block along a horizontal floor can be calculated using the equation: **F = μN** where F is the force of friction, μ is the coefficient of sliding friction, and N is the normal force.

In this case, the normal force can be calculated using the equation: **N = mg** where m is the mass of the block and g is the acceleration due to gravity.

Given that the mass of the block is 25 kg and the coefficient of sliding friction is 0.19, the force required to move the block can be calculated as follows: **F = (0.19)(25 kg)(9.8 m/s²) = 46.05 N**

Therefore, the force required to move the block is 46.05 N, the correct answer is **46.6 N**.

When trying to move a 25kg block along a horizontal floor, the force required is essential to understand the amount of effort needed. The coefficient of sliding friction, in this case, is given as 0.19, which affects the force needed to overcome the friction between the block and the floor.

By calculating the force required using the equations for friction and normal force, we can determine the exact amount of force needed to move the block successfully. In this scenario, the force required is 46.05 N, or rounded to the nearest whole number, 46.6 N.

Understanding the physics behind friction and force required for motion is crucial in various real-world applications, such as engineering and mechanics. By mastering these concepts, individuals can optimize their efforts and resources to achieve efficient movement and operation.
