Question

Find the weight of a person whose mass is 72 kg. ​

Answer 1

Answer:

705.6N

Explanation:

Weight = mass x acceleration due to gravity

W = mg

(g=9.8m/s^2)

W = 72 x 9.8 = 705.6N

Answer 2

Given:

Mass of the person = 72 kg

To find:

The weight of the person

Solution:

We know that the acceleration due to gravity is 9.8 m/s²

So the weight of the person = Mass of the person × Acceleration due to gravity

Therefore, the weight of the person = 72 kg × 9.8 m/s² = 705.6 N

( where 'N' is the SI unit of weight, Newton )

Hence, the weight of a person with a mass of 72 kg is 705.6 N.
