Answer:
If jack is in the piece of furniture it would submerge.
Explanation:
The piece of furniture would submerge if the weight applied on the furniture is greater than the maximum buoancy force the water can provide.
maximum buoacy force = density of liquid × volume submerged× acceleration due to gravity.
=
v = area × thickness of pine
= 0.075
therefore buoancy force = 1025×0.075×9.8 N
= 753.375 N
weight of rose alone = 46×9.8 N = 450.8 N
weight of jack alone = 58×9.8 = 568.4 N
weight of pine = density of pine × volume of pine
= 350 × 0.075= 26.25 N
weight of pine + weight of rose = 450.8+26.25=477.05 N
weight of pine + rose + jack = 477.05 + 568.4 = 1045.45 N
therefore if jack is in the piece of furniture it would submerge.
