A person with a mass of 80 kg has a force of gravity from the earth on them of about 800 N. This person is standing on a scale while in an elevator that is moving upwards but slowing down with an acceleration of 1 m/s2. What value does the scale read?

Respuesta :

Answer:

So scale will read a force force of 880 N

Explanation:

We have given that mass of the person m = 80 kg

Force of gravity from the earth F = 800 N

We know that force is given by [tex]F=mg[/tex]

So [tex]800=80\times g[/tex]

[tex]g=10m/sec^2[/tex]

It is given that acceleration of the elevator a = [tex]1m/sec^2[/tex]

We have to find the force which scale read

So force is given by [tex]F=m(g+a)=80(10+1)=880N[/tex]

So scale will read a force force of 880 N
