Question

The feather experiences 0.075 N of downward force. Assuming it is on earth, what is its mass?

Answer 1

The mass of the feather would be 0.0075 kg.

Step-by-step explanation:

If the feather were to be on earth, it would have experienced the gravitational pull of the earth downwards. So that from Newton's second law of motion,

F = mg

where f is the force on the object, m is the mass of the object and g is the acceleration due to gravity of the earth.

But, F = 0.075 N, g = 10 m/
`s^(2)`.

So that,

0.075 = m x 10

m =
`(0.075)/(10)`

= 0.0075 kg

The mass of the feather would be 0.0075 kg.
