[QUOTE="Astraithious, post: 5154683, member: 542700"] [h2]Homework Statement [/h2] A 0.057 kg tennis ball moving west at 24 m s is hit in the opposite direction east with a tennis racket. The force acting on the ball during the hit is shown in the graph below. [ATTACH=full]85336[/ATTACH] What is the magnitude of the final momentum of the tennis ball? [B]A. 0.63 kgm s[/B] B. 1.37 kgm s C. 1.80 kgm s D. 3.37 kgm s [h2]Homework Equations[/h2] f(tf-ti)=m(vf-vi)= change in momentum=impulse[/B][h2]The Attempt at a Solution[/h2]so I assumed that I could find final velocity going east by doing this f ( tf - ti )= m ( vf - vi ) 80 ( 0.06-0.02 ) = 0.057 ( vf - (-24) ) 3.2 = 0.057 ( vf - (-24) ) 56.14 = vf - (-24) vf=32 m/s so momentum right is (0.057)(32)=1.824 kg*ms left is (0.057)(-24)= -1.368 kg*ms final is 1.824 + (-1.368) = .456kg*ms to the right this is incorrect so I'm not sure where i went wrong, I'm sure its simple but it escapes me. thanks for any insight [/QUOTE]
