Question

Mr. Lineberry buys a new saw for his woodshop. The tool has a weight of 255 N. What is the mass of the tool in kg?

Answer 1

Given:

The weight of the saw is: W = 255N.

To find:

The mass of the saw.

Step-by-step explanation:

The weight is the force that acts on the mass m due to the gravity of the earth. It is measured in Newtons.

The expression for the Weight force W is:

W = mg

Here, m is the mass of the body/object/particle, and g is the acceleration due gravity of the earth. The value of acceleration due to the gravity of the earth is 9.8 m/s^2

Substitute the values in the above equation, we get:

255 N = m × 9.8 m/s^2

Rearranging the above equation and simplifying it, we get:

`\begin{gathered} m=\frac{255\text{ N}}{9.8\text{ m/s}^2} \\ \\ m=\frac{255\text{ kg.m/s}^2}{9.8\text{ m/s}^2} \\ \\ m=26.02\text{ kg} \end{gathered}`

Final Answer:

The mass of the saw is 26.02 kg.
