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 θ =30° above the horizontal. The coefficients of friction between the plane and the box are μ 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 μ s, what is the maximum angle the plane can be tilted if the box remains at rest? PHYS 1100 Spring 2012...
