Question

A woman weighs 580 N. What is her mass?

Answer 1

Answer:

Mass, m = 59.18 kg

Explanation:

It is given that,

Weight of a woman, W = 580 N

To find,

Mass of woman

Solution,

We know that the weight of an object is the force of gravity acting on an object. It is equal to the product of mass and acceleration due to gravity on the Earth's surface,

W = mg

$m=\dfrac{W}{g}$

$m=\dfrac{580\ N}{9.8\ m/s^2}$

m = 59.18 kg

So, the mass of the woman is 59.18 kg.

Answer 2

w = mg where g = 9.8 N/kg  

m = 580/9.8 = 59 kg
