A 61.0-kg survivor of a cruise line disaster rests atop a block of Styrofoam insulation, using it as a raft. The Styrofoam has dimensions 2.00 m ✕ 2.00 m ✕ 0.0860 m. The bottom 0.026 m of the raft is submerged.
(a) Draw a force diagram of the system consisting of the survivor and raft. (Submit a file with a maximum size of 1 MB.) This answer has not been graded yet.
(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. (Set a = 0. Solve for Fy, the y-component of the net force. Let upward be the positive y-direction.) Fy = = 0
(c) Calculate the numeric value for the buoyancy, B. (Seawater has density 1025 kg/m3. Enter answer to at least the ones digit.) 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

B. Floating, wooden block s 13. Remove the brick block from the water.be 14. Use the scale to determine the weight of the wood block out of water. 49.00 N 15. Note the exact water level reading in the container of water and record the reading below. 100.00L 16. Now, complete submerge the wooden block in the water and hold it there under the water with the mouse. Note the new water level reading in the container of water and...
A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.
A raft is made of 11 logs lashed together. Each is 38.0 cm in
diameter and has a length of 7.00 m. How many people (whole number)...
