Newton’s Laws + Friction Problems
1. A man pulls a 300 N object across a horizontal surface using a 200 N force applied at a 20° angle. What is the normal force? If the object is pulled with an acceleration of 1.2 ms-2, what is the coefficient of friction?
2. A man pulls a 60 N object across a horizontal surface using a 80 N force applied at a 45° angle. What is the normal force? If the coefficient of friction is 0.22, what is the acceleration of the object?
3. A man now pushes a 500 N object across a horizontal surface using a 200 N force applied at a 35° angle. What is the normal force? If the object is pulled with an acceleration of 1.8 ms-2, what is the coefficient of friction?
4. A man pushes a 80 N object across a horizontal surface using a 50 N force applied at a 12° angle. What is the normal force? If the coefficient of friction is 0.15, what is the acceleration of the object?
