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=(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*9.8 \\ W=728.9\text{ N} \end{gathered}`

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