Question

1. a force of 100 n is used to push an object 5 m in 15 seconds. find the work done and the power.

100 j, 5 w
200 j, 10 w
1,000 j, 67 w
500 j, 33 w

Explanation:

Step1: Calculate work done

Work \(W = F\times d\), where \(F = 100\ N\) and \(d=5\ m\).
\(W=100\times5 = 500\ J\)

Step2: Calculate power

Power \(P=\frac{W}{t}\), where \(W = 500\ J\) and \(t = 15\ s\).
\(P=\frac{500}{15}\approx33\ W\)

Answer:

500 J, 33 W
