Unformatted text preview: and the magnitude of the friction force? PHYS 1100 Spring 2012 GW2: A force F pushes on a box of mass m that initially is at rest on a rough, horizontal surface. The force F is directed at an angle =30 above the horizontal. The coefficients of friction between the plane and the box are s=0.30 and k=0.28. If F =50 N and m =15 kg, what is the acceleration of the box and the magnitude of the friction force? PHYS 1100 Spring 2012 EX2: A box of mass m rests on a plane inclined at an angle above the horizontal. If the coefficient of static friction between the plane and the box is s, what is the maximum angle the plane can be tilted if the box remains at rest? PHYS 1100 Spring 2012...
