Question

It takes 25N or force to drag a box along the floor at a constant speed. If the coefficient of friction is .3, what is the mass of the box?

Answer 1

The mass of the box is 8.5 kg.

What is mass?

Mass can be defined as the quantity of matter contained in a body.

To calculate the mass of the box, we use the formula

Formula:

• F = mgμ............. Equation 1

Where:

• F = Force
• m = mass of the box
• g = acceleration due to gravity
• μ = coefficient of friction

Make m the subject of the equation

• m = F/gμ..................... Equation 2

From the question,

Given:

• F = 25 N
• g = 9.8 m/s²
• μ = 0.3

Substitute these values into equation 2

• m = 25/(0.3×9.8)
• m = 25/2.94
• m = 8.5 kg

Hence, the mass of the box is 8.5 kg.
