QUESTION 3 A Type I offshore life jacket (i.e. personal flotation device) is the type worn by commercial fishermen - it is designed for extended survival in rough, open seawater. Consider such a life jacket that uses an impermeable foam material with a density of 32 kg/m³ - the other parts of the life jacket (straps, fasteners, etc) weigh 0.6 kg and are of negligible volume to the design. a) Draw a free body force diagram for the life jacket. b) Determine the minimum volume of foam material (in L) that is needed for the life jacket in order to provide a minimum 98 N net upward force when it is fully submerged in seawater (as required by US Coast Guard regulations).
