Question

An astronaut weighs 164 lb. What is his weight in newtons?TEN

Answer 1

Given data:

* The mass of the astronaut is m = 164 lb.

Solution:

The mass of the astronaut in kg is,

$\begin{gathered} m=\frac{164}{2.205} \\ m=74.38\text{ kg} \end{gathered}$

The weight of the astronaut in newtons is,

$\begin{gathered} W=mg \\ W=74.38\times9.8 \\ W=728.9\text{ N} \end{gathered}$

Thus, the weight of the astronaut in Newton is 728.9 N.
