Question

a block of mass 4 kg is resting on a rough horizontal plane and is
about to move when a horizontal force of 30 N is applied on it if g
= 10 m/s^2 find the total contact force exerted by the plane on the
block

Dear student,

F=30Nm=4kgso F=maa=Fm=304=7 5m/s2μ=ag=7
510=34Contact force= Frictional force=μmgF=34×4×10=30NContact force=30N
