Block A in the figure weighs 460 N The coefficient of stati

Block A in the figure weighs 46.0 N . The coefficient of static friction between the block and the surface on which it rests is 0.30. The weight w is 7.00 N and the system remains at rest.(Figure 1)

Part A

Find the friction force exerted on block A .

Express your answer in newtons to three significant figures (N)

Part B
