Answer:
a) 68.9 b/ ft²
b) 57.416
Explanation:
Volume of the cylindrical open container V = 5 gal
= (5)(231)
= 11155 in³
different diagrammatic expression has been shown in the attached file below for clear understanding.
Area A = 120 in²
V = hA
=
= 9.625 in
Upward acceleration ,
= 68.9 b/ ft²
b) The flowchart for the resultant force is shown in the diagram below:
with that:
Thus, the resultant force that the container exert on the floor of the elevator during this acceleration = 57.416
