Question

Determine the normal force when the frictional force is 250 N and the coefficient of friction between the box and the table is 0.4

Answer 1

Friction force = Normal Force x coefficient of friction

Friction Force = 250N

Coefficient of friction = 0.4

Replacing with the values given:

250N = N * 0.4

N = 250N/0.4 = 625 N

Normal Force = 625N
