A267.5 n unbalanced force applied to push a stuffed chair across the room, causing an acceleration of 4.2 m s2 . what is the mass of the chair?

Hi,

Data:

                          Force= F=                     267.5 N

                          Acceleration=a=           4.2 m s2 .

                          Mass of the chair= m=    ?

As we know that, according to second law of motion.

                                                  F= ma

Putting the values from the data:

                                         267.5          = m (4.2 )

                                          267.5/4.2   = m

                                          63.69         = m

                                          Mass=   63.7 kg

So, the mass of the chair will be 63.7 kg.

Hope it helps:)
