Solve for problem #2 1)A round fishing bobber floats with 25% of its volume below the water. The boober has a radius 2.0 cm.Initially, the fishing lines are slack, and make no forces on the bobber. The weight of the hook, line, andbait is negligible.a) How large is the bouyant force on this bobber?b) If a fish bites and pulls the bobber completely under water. What's the minimum downward pullingforce applied by the fish to the bobber?2)A pipe filled with water has a gauge attached to it. The gauge reads a pressure of 4.00 atm.a) How large is the absolute pressure inside this pipe?b) A small hole is made in the pipe. At what speed does the water emerge through the hole?3)A 250g mass is mounted on a spring that exerts a force of 5.00N when stretched by 2.00 cm. The wasis pulled to the right by 5.00cm and then released.a) Find the spring constant:b) Find the frequency of oscillations:c) Find the period of oscillations:d) Find the amplitude of oscillationse) Find the maximum velocity of m when passing x-0:

Given Data: The gauge pressure inside the pipe is Pg = 4 atm. Part (a): The absolute pressure inside the pipe can be determined as, Pa=Pg+PatmPa=4 atm+1 atmPa=5 atm×101325 Pa1 atmPa=506625 Pa Thus, the required value of absolute pressure in the pipe is 506625 Pa.Part (b): When a small hole is made in the pipe all gauge pressure head gets converted into the kinetic head, hence the speed of the water can be determined as, Pgρg=V22gV=2PgρV=2×4 atm×101325 Pa1 atm1000 kg/m3V=28.47 m/s Thus, the speed of water is 28.47 m/s.
