Question

a person attempts to push a massive rock with a force of 500 n for 10 seconds. the rock does not move. the work done by the person on the rock is _______

Explanation:

Step1: Recall the formula for work

Work \( W = F\times d\times\cos\theta\), where \(F\) is the force, \(d\) is the displacement, and \(\theta\) is the angle between the force and the displacement.

Step2: Analyze the displacement

Since the rock does not move, \(d = 0\).

Step3: Calculate the work

Substitute \(d = 0\) into the work formula: \(W=500\times0\times\cos\theta = 0\) (regardless of the value of \(\theta\) as the displacement term makes the product zero).

Answer:

\(0\space J\)
