Question

two friends were travelling by car from culpepper to fredericksburg when their car overheated. they applied 900 n of force to push the 3000 n car, but they were unable to move it. how much work did they do?
0 j
450 j
900 j
3000 j

Explanation:

Step1: Recall the work formula

Work \(W = F\times d\). Here, the displacement \(d = 0\) (since they were unable to move the car).

Step2: Calculate work

Substitute \(F = 900\space N\) and \(d=0\space m\) into the formula \(W = F\times d\). So \(W=900\times0\).

Answer:

\(0\space J\)
