Answer:
The answer is 0.8 m
Explanation:
According the attached diagram, if we take the momentum in the point 0:
[tex]\frac{m_{D}*5.1 }{2} =m_{J} *X[/tex]
Where
mD = mass of Diane = 64.2 kg
mJ = mass of Jack = 93.6 kg
Replacing:
[tex]X=\frac{\frac{64.2*5.1}{2} }{93.6} =1.75m[/tex]
[tex]\frac{L}{2} -X=Y=\frac{5.1}{2} -1.75\\Y=0.8m[/tex]
