Question

1. a force of 100 n is used to move an object 15 m with a power of 25 w. find the work done and the time it taken.

Explanation:

Step1: Calculate work done

Work formula: \(W = F\times d\). Given \(F = 100\ N\), \(d=15\ m\).
\(W=100\times15 = 1500\ J\)

Step2: Calculate time taken

Power formula: \(P=\frac{W}{t}\), so \(t = \frac{W}{P}\). Given \(P = 25\ W\), \(W = 1500\ J\).
\(t=\frac{1500}{25}=60\ s\)

Answer:

1,500 J, 60 s
