Determine the minimum force P that is required to move both objects.

Solution

frictional resistance = nu*F

Where, nu= coefficent of static friction

F= Normal force

Minimum force required to move both objects \'P\" can be calculted as

P= Friction resistance from object C+Frictional resistance from object A

P=(nu)_C*F_C+FA*(nu)_A

P=0.2*245+0.5*125=111.5 N
