Question
Part A A block lies on a plane raised an angle e fram the horizantal. Three forces act upon the block: Fw, the force of gravity. Fn. the narmal force; and Fr. the force of friction. The coefficient of friction is large enaugh to prevent the block from sliding (Figure 1). Consider coordinate system a, with the x axis along e plane. Which forces lie along the axes? O Ée arly O F, anly O F. only O ři and F. O ř and F. O řa and F. O ř and řa and ř. Submit Requect Ancwor Part B Which forces lie along the axes af the coordinate system b, in which the y axis is vertical? O F anly O F. anly O F. only O F and P, O ř and F. O F, and F. O řr and Fa and Ě, Submit Request Answer Usually the best advice is to choose a coordinate system so that the acceleration of the system is directly along one of the coordinate axes. If the system isn't accelerating, then you are better off choosing the coordinate system with the most vectors along the coordinate axes. But now you are gaing to ignore that advice. You will find the normal force, F, using vertical coordinate system b. In these coordinates you will find the magnitude F appearing in both the X and y equations, each multiplied by a trigonometric function. • Part C Because the block is not moving, the sum of the V components of the forces acting on the black must be zerp.
