1. The problem statement, all variables and given/known data Jack and Jill are maneuvering a 3570kg boat near a dock. Initially the boat's position is [PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmsy10/alpha/144/char68.png2,0,9[PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmsy10/alpha/144/char69.pngm [Broken] and its speed is 4.6m[PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmmi10/alpha/144/char3D.pngs. [Broken] As the boat moves to position [PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmsy10/alpha/144/char68.png12,0,0[PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmsy10/alpha/144/char69.pngm, [Broken] Jack exerts a force of [PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmsy10/alpha/144/char68.png-80,0,290[PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmsy10/alpha/144/char69.pngN, [Broken] and Jill exerts a force [PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmsy10/alpha/144/char68.png0,240,0[PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmsy10/alpha/144/char69.pngN. [Broken] What is the final speed of the boat? 2. Relevant equations W=Fd Kfinal = Kinitial +W KE=(1/2)mv^2 3. The attempt at a solution 1) Final total work Jack Work = (-80*10)+(0*0)+(290*-9) = -3410 Jill Work = 0 (It says my Work is correct) 2) Kfinal = Kinitial + W Kinitial = (1/2)(3570)(4.6)^2 = 37770.6 Kfinal = 37770.6+(-3410) Kfinal = 34360.6 3) Final Velocity = KE/m 34360.6/3570 = 9.6248m/s Not sure where my error is... any help would be appreciated!
