##### Question

# A 62 kg survivor of a cruise line disaster rests atop a block of Styrofoam insulation, using it…

(b) Write Newton's second law for the system in one dimension, using B for buoyancy, w for the weight of the survivor, and wr for the weight of the raft. (Use anyvariable or symbol stated above as necessary.)

Fy =

(c) Calculate the numeric value for the buoyancy, B. (Seawater has density 1025 kg/m3.)

N

(d) Using the value of B and the weight w of the survivor, calculate the weight wr of the Styrofoam.

N

(e) What is the density of the Styrofoam?

kg/m3

(f) What is the maximum buoyant force, corresponding to the raft being submerged up to its top surface?

N

(g) What total mass of survivors can the raft support?

kg
