Figure 7-39 gives the acceleration of a 1.90 kg particle as it ismoved from rest along anx axis by an applied forceFa,from x = 0 to x =9 m.How much work has the force done on the particle when theparticlereaches the following points?(a) x = 4 m
1 J
(b) x = 7 m
2 J
(c) x = 9 m
3 J
What is the particle's speed and direction of travel when itreacheseach of the following points?(d) x = 4 m
4 m/s --Direction--+x-x
(e) x = 7 m
6 m/s --Direction--+x-x
(f) x = 9 m
8 m/s --Direction--+x-x
