• Practice D 1-3 page 139 
• Practice E 1-4 page 141

when you push an object or pull an object with NO angle...... Normal Force = mass * acceleration due to gravity

when you have an angle, you have to take into account the F in the y direction and if you are PULLING IT you add F in y to the Normal force to equal mg and if you are pulling it....Normal Force=mg + Force in the y
