Question

Friction coefficient of friction support force, sliding or static coefficient F and angle in polar format F cos-angle and F sin-angle in Cartesian x y format Vector and angle in polar format - Vector cos-angle and Vector sin-angle in Cartesian x-y format Force, velocity, acceleration are vector examples A system consisted of two objects sitting on a floor, a 15 kg object on top with a 50 kg object at the bottom. The sliding coefficient of friction between the two objects was 0.3. A 20N force was used to pull the 15-kg object. Determine the floor static coefficient of friction such that the 50 kg object was at rest A system consisted of two objects sitting on a floor, a 15 kg object on top with a 50 kg object at the bottom. The sliding coefficient of friction between the two objects was 0.3. A 20N force at 10 degree to the horizontal direction was used to pull the 15-kg object. Determine the floor static coefficient of friction such that the 50 kg object was at rest. would it be larger than the answer in #1, explain? A system consisted of two objects sitting on a floor, a 15 kg object on top with a 10 kg object at the bottom. The sliding coefficient of friction between the two objects was 0.3. The floor sliding coefficient of friction was 0.2. Determine the force applied to the 15 kg top object such that both objects had 0.5 m/s/s acceleration A system consisted of two objects sitting on a floor, a 15 kg object on top with a 10 kg object at the bottom. The sliding coefficient of friction between the two objects was 0.3. The floor sliding coefficient of friction was 0.2. Determine the force applied to the 10 kg yp object such that both objects had 0.5 m/s/s acceleration.
