## Question:

A boy A having weight ${ W }_{ A }$ and a girl B having weight ${ W }_{ B }$ stand motionless at the ends of the toboggan, which has weight ${ W }_{ t }$. If A walks to B and stops, and both walk back together to the original position of A (both positions measured on the toboggan), determine the final position of the toboggan just after the motion stops. Neglect friction. Given: ${ W }_{ A }$ = 80 lb , ${ W }_{ B }$= 65 lb , ${ W }_{ t }$= 20 lb , d = 4 ft
