A heavy box of mass 50 kg sits at rest on a floor. the coefficients of static and kinetic between the box and?

the floor are 0.4 and 0.35 respectively a force of 150 N is applied horizontally to the box. the box will





a. move at a constant velocity


b. accelerate


c. remain at rest forever


d. remain at rest for 2 s and then accelerate

A heavy box of mass 50 kg sits at rest on a floor. the coefficients of static and kinetic between the box and?
Answer would be C. It would stay at rest.





150N is not sufficient to overcome static friction. It actually is not sufficient to overcome kinetic friction either.
Reply:the mass = 490.5 N,so i dont think a horizontal force of 150 N would be enough to over come friction so would remain at rest.But im no good at mechanics
