Question

a block of granite has a mass of 15.0 kg. what is the magnitude of its weight (the gravitational force) near the earths surface? (assume g = 9.8 m/s2)

Explanation:

Step1: Recall the formula for weight

Weight \( W = m\times g\), where \(m\) is mass and \(g\) is acceleration due to gravity.

Step2: Substitute the given values

Given \(m = 15.0\space kg\) and \(g=9.8\space m/s^{2}\). Then \(W=(15.0\space kg)\times(9.8\space m/s^{2})\).

Step3: Calculate the result

\(W = 147\space N\)

Answer:

\(147\space N\)
