Question

a student pushes a 40 - n block across the floor for a distance of 10 m. how much work was done to move the block? 4 j 40 j 400 j 4,000 j

Explanation:

Step1: Recall the work formula

Work \( W = F\times d\), where \(F\) is force and \(d\) is distance.

Step2: Substitute values

Given \(F = 40\space N\) and \(d=10\space m\). Then \(W=40\times10\).

Step3: Calculate

\(W = 400\space J\)

Answer:

400 J
