Question

1. a person has a mass of 50 kg.

what is their weight on earth? show your work.
weight = mass × 9.8 m/s²
weight = _ × _ = ___ n

Explanation:

Step1: Recall the formula for weight

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

Step2: Substitute the given values

Given \(m = 50\space kg\) and \(g=9.8\space m/s^{2}\). Then \(W=50\times9.8\).

Step3: Calculate the result

\(50\times9.8=(5\times10)\times(9.8)=5\times(10\times9.8)=5\times98 = 490\)

Answer:

\(490\space N\)
