Question

A block of mass 2kg is on a horizontal surface.The coefficient of static and kinetic friction are 0.6 and 0.2 The minimum horizontal force required to start the motion is applied and

Answer 1

as friction is equal to mu *normal( mass*gravity)

friction =0.6*2*10=12 N

so force applied to move should be more than 12 N which can be 13 N also
