given the normal reaction on floor is 3N

SO m(g+a)=3           m is mass of cheese

 a =2 m/s2

we know work done =F.S

                            = mas                                  ( a=g+a

                            =900.25x 12x 2.4

                            =25.9 kj                                                =12)
