On an SI scale, an object weighs 14 N. If the object is on earth and accelerating downward at a rate of 9.8 m/s?,then what must be the mass of the object in kg?Round your answer to the nearest decimal.

Respuesta :

We have the next formula

[tex]W=mg[/tex]

W is the weight, m is the mass and g is the gravity.

In our case

W=14N

g=9.8 m/s^2

We substitute the values

[tex]14=m(9.8)[/tex][tex]m=\frac{14}{9.8}=1.4\text{ kg}[/tex]

ANSWER

m=1.4 kg
