Question

A man has a mass of 150 kg. What does he weigh on earth expressed in N?

Answer 1

1470 N

Explanation:

Given:

Mass (m) = 150 kg

Earth gravity (g) = 9.8 m/s²

We can calculate the weight as follows:

`\begin{gathered} W=m\cdot g \\ \\ \text{ We replacing:} \\ \\ W=150\cdot9.8 \\ \\ W=1470\text{ N} \end{gathered}`

The weight of this man on earth is 1470 N
