A force F. is applied to a bead as the bead is moved along
Chapter 7, Problem 6(choose chapter or problem)
A force F. is applied to a bead as the bead is moved along a straight wire through displacement +5.0 cm. The magnitude of F. is set at a certain value, but the angle between F. and the bead's displacement can be chosen. Figure 7-23 gives the work W done by Fa on the bead for a range of values; Wo = 25 J. How much work is done by F. if is (a) 64 and (b) 147?
