Question

A force of 560.0 N is needed to produce an acceleration of 20 m/s2. What is the mass of the object?

Answer 1

Given,

The force needed, F=560.0 N

The acceleration produced, a=20 m/s²

From Newton's second law, the force applied to an object is equal to the product of the mass of the object and the acceleration produced due to the applied force.

Thus,

`F=ma`

Where m is the mass of the object.

On substituting the known values in the above equation,

`\begin{gathered} 560.0=m*20 \\ \Rightarrow m=(560)/(20) \\ =28\text{ kg} \end{gathered}`

Therefore the mass of the object is 28 kg
