Question

What is the weight of a 90kg man standing on Earth, where gᵉᵃʳᵗʰ = 9.82 m/s^2?

Answer 1

`88.38 Kgm/s^2`

Step-by-step explanation:

Mass and weight are quite different terms .

Weight is defined as the amount of force exerted on the earth due to our mass and gravity of acceleration.

`W=m*g`

Given that the mass is 90 kg and gravity of acceleration of earth is 9.82 m/s^2.

So weight will be

`W=90*9.82\\\\ W=88.38 Kgm/s^2`

So this is the weight of the 90kg man standing on earth.
