Question

A body starts from rest and acquire a velocity v in time t. The work done on the body in time t will be proportional to

Answer 1

I think its mass because v = 0 + at ,

a=v/t

we know,

Workdone in time t (w/t) =Fs/t

                                        =ma(s/t)

                                         =m*v/t*v

  v and t are known so, the work done on the body in time is proportional to m
