Question

Rebekah has a table that has a mass of 21.7 kg. What is the weight of the table?

A. 6 N
B. 31.5 N
C. 9.8 N
D. 212.66 N

Answer 1

D I believe because the gravitational pull is 9.8 m/s so
w=mg
w=21.7*9.8
w=212.66 N

Answer 2

D. 212.66 N

Step-by-step explanation:

The weight of an object is the force exerted by the gravitational acceleration due to earths gravity on it, and mass is simply the amount of matter that said object has, which is usually measured in kilograms.

The formula to calculate the weight of an object is

`w = mg`

where
`m` is the mass and
`g` is the gravitational acceleration
`g=9.8m/s^2`

So for this case, if the table has a mass of
`21.7 kg`

the weight will be:

`w=(21.7 kg)(9.8m/s^2)=212.66N`
