Question

Mrs. J . weighs 557 N. what is her mass?

Answer 1

her mass is 55.7 Kg.

Step-by-step explanation:

Weight = Mass × Acceleration

N =ma [a= g for gravitational force acting down word]

N=Mg

find M so make mass become the subject therefore,

Mass = force / gravitational acceleration [let g=10m/s^2]

m=557 / 10

m= 55.7 kg

Answer 2

The mass of the person is 56.83 kg

Step-by-step explanation:

W= 557 N

We know that acceleration due to gravity (g)= 9.8 m/s^2

Now,

W= mass * acceleration due to gravity

557=m * 9.8

m= 557/9.8

m= 56.83
