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:)

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
