coefficient of friction is given as
[tex]\mu_s = 0.42[/tex]
mass of the object is
[tex]m = 45 kg[/tex]
now the maximum friction force on it given by
[tex]F_s = \mu_s mg[/tex]
[tex]F_s = 0.42 \times 45 \times 9.8[/tex]
[tex]F_s = 185.22 N[/tex]
so here it is similar to hold a 18 kg mass in hand which is possible to hold
So here we can slide the box on the floor.
