Question

A woman weighs 120 lb. Determine her weight in newtons.

Answer 1

M= 120 lb = 54.4 kg

weight = $F_{n}$
$F_{n}$ = mg
= (54,4 kg)(9.8 m/s^2)
=  533.12 N

Answer 2

The weight of the woman in Newton is $\boxed{532.73{\text{ N}}}.$

Further Explanation:

The formula for the force can be expressed as follows,

$\boxed{F = m \times a}$

Here, F represents the force, m represents the mass and a represents the acceleration.

The formula for the weight can be expressed as follows,

$\boxed{W = m \times g}$

Here, W is the weight, m is the mass and g is the acceleration due to gravity.

Given:

The weight of the woman is $120{\text{lb}}.$

Explanation:

First convert the unit of mass in kilogram.

$1{\text{lb}} = 0.453{\text{ kg}}$

Multiply 120 by 0.453 to obtain the mass in kilogram.

$\begin{aligned}{\text{weight}}&= 120\times 0.453\\&= 54.36{\text{ kg}}\\\end{aligned}$

The weight of the woman in newton can be obtained as follows,

$\begin{aligned}{\text{W}} &= 54.36 \times 9.8\\&= 532.73{\text{ N}}\\\end{aligned}$

The weight of the woman in Newton is $\boxed{532.73{\text{ N}}}.$
