Name__________________________________ Archimede’s Principle 1) A raft is constructed of wood having a density of 600 kg/m 3 . Its surface area is 5.7 m 2 and its volume is 0.60 m 3 . When the raft is placed in fresh water of density 1.0 x 10 3 kg/m 3 to what depth does the raft sink in the water? 2) A spherical helium balloon of radius 0.15 meters is released into the atmosphere. Determine the acceleration of the balloon if the density of helium is 1.79 x 10 -1 kg/m 3 , the density of air is 1.29 kg/m 3 , and the empty balloon has a mass of 0.012 kg. (assume there is no resistive force acting on the balloon)

3) A basketball filled with air is released from the bottom of a 3 meter deep pool w =1000 kg/m 3 ). The mass of the basketball filled with air is 0.660 kg and the radius is 0.17 meters. Determine the time it takes for the ball to reach the surface of the pool. 4) A hollow sphere of mass 0.01 kilograms is filled with helium (ρ

Determine the tension in the string if the radius of sphere is 0.10 meters. 5) A solid foam ball (ρ= 100 kg/m 3 ) of radius 0.15 meters is dropped from a height of 3 meters above the surface of a pool (ρ= 1000 kg/m 3 ). Neglecting air resistance and any fringe effects(as the ball enters the pool) determine: (a) the acceleration of the ball while its in the air (density of air = 1.29 kg/m 3 ) (b) the velocity of the ball just before it hits the water (c) the acceleration of the ball while it is in the water (d) the depth to which the ball goes before stopping 6) A block of wood of mass 30 kg is floating in a pond of density 1000 kg/m 3 such that half of the block is submerged. Determine the density of the object....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
