Question
A 260.5N unbalanced force applied to push a chair across the room causing an acceleration of 4.2 m/s2. What is the mass of the chair?2 marks263.3 kg63.69 kg62.02 kg1123.5 kg
Solution
To find the mass of the chair, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = ma).
Given: Force (F) = 260.5 N Acceleration (a) = 4.2 m/s^2
Using the formula F = ma, we can rearrange it to solve for mass (m): m = F / a
Substituting the given values: m = 260.5 N / 4.2 m/s^2
Calculating the result: m ≈ 62.02 kg
Therefore, the mass of the chair is approximately 62.02 kg.
