A wooden cylinder is floating in water. The length of the cylinder is 40 cm and diameter is 14 cm. The density of wood is 0.38 gm/cc. At the equilibrium position the cylinder makes 30 degree with the surface of water. Find the length of cylinder submerged in water (both the longer and shorter side - when you imagine a 2D picture of the submerged cylinder, there is a shorter length and a longer length submerged in water).

2. A short metal cylinder of radius 24.0 cm, height 5.5 cm, and mass 4.25 kg is positioned on a flat surface with a frictionless pivot point at its center. A string is fixed to the outside of the cylinder and wrapped around several turns before leaving the cylinder and running parallel to the surface to a pulley which supports a hanging mass of 1.40 kg. The system is released from rest at time t0 (25) Calculate the angular acceleration...

1. A cylinder of mass m, height h and radius r floats partially submerged in a liquid of density ρ. One third of the height of the cylinder is above the surface of the water. Johnny pushes the cylinder down by a small distance x<h/3, then he releases it from rest. A) prove that the resulting motion of the cylinder is a simple harmonic motion. B) Find the period of the small oscillations in terms of the given quantities (m,r,h,ρ)...

A particular cylindrical bucket has a height of 50.0 cm, and the radius of its circular cross-section is 15 cm. The bucket is empty, aside from containing air. The bucket is then inverted so that its open end is down and, being careful not to lose any of the air trapped inside, the bucket is lowered below the surface of a fresh-water lake so the water-air interface in the bucket is 40.0 m below the surface of the lake. To...

Write your answers (with appropriate precision) in the blanks provided. Indicate all units. 5. You use a string to rotate a 30-g cork. The other end of the string is threaded through a glass tube, and a 200-g mass is suspended at the bottom. This keeps the tension in the string constant. Use information to fill out the missing entries in...

A thin spherical shell has a mass of 2 kg when it is empty, radius 0.2 meters, and a volume of 0.0335 m3. It is filled with helium (density=0.179 kg/m3) and released from rest at the bottom of a pool of water that is 4 meters deep. (density of water= 1000 kg/m3). 1. Show that the shell rises with constant acceleration and determine the acceleration. 2. How long does it take the top of the shell to reach the water...

A cube of wood having an edge dimension of 22.1 cm and a density of 651 kg/m^3 floats on water. What is the distance from the horizontal top surface of the cube to the water level? If a block is floating, the buoyant force must equal the weight of the block cm What mass of lead should be placed on the cube so that the top of the cube will be just level with the water surface? The block is...
