Question

19 a rock has a mass of 15 kg, what is the rocks approximate weight? a 15 n b 120 n c 1.5 n d 147 n

Explanation:

Step1: Recall the formula for weight

Weight \( W = mg\), where \(m\) is mass and \(g\) is acceleration due to gravity (\(g = 9.8\space m/s^{2}\))

Step2: Substitute the values

Given \(m = 15\space kg\) and \(g = 9.8\space m/s^{2}\), then \(W=15\times9.8\)
\(W = 147\space N\)

Answer:

D. 147 N
