Question

i need the 2 answers. please

Answer 1

You are given a unit conversion : 1 Kg = 2.2 Lbs

 

First questions asks, What is your mass in (Kg)

 

Since you are on the earth, the acceleration of Gravity is 9.8 m/s^2

The formula for weight of any object is W = m*g, where W = Weight in Newtons( N )

                                                                                  m = Mass in (Kg)

                                                                                   g = Acceleration of gravity on the specific planet, Earth is

                                                                                         9.8 (m/s^2)

 

So what ever your weight is lets say 160 lbs, convert it to Kg:  kg = 160lbs * ( 2.2 Kg / 1 lb ) = 352 kg which is your mass.

 

 Answer to A) Mass = 352 Kg

 

Hence your weight  ( W = m*g ) is (352kg) * ( 9.8 m/s^2 ) = 3449.6 Newtons

 

 Answer to B) Weight = 3449.6 Newtons
