2. A cylindrical object—with radius R, length L, and density ??—sits on a scale at the bottom of vat of fluid with density??.a. Draw and label a free body diagram for the object. (Don’t forget to set up a coordinate system and to label the acceleration info. Also, be sure to use the gridlines to help you draw arrows that show the correct directions and relative magnitudes of the forces. Finally, be sure to label your forces clearly to indicate the types of forces.)b. Use Newton’s 2nd Law to derive an expression for the reading on the scale.
A cylindrical steel tank with a diameter of 20.0 cm, a length of 150.0 cm, and an overall mass of 150.0 kg is accidently dropped into a lake. What is the cylinder's density in g/cm3? Will it sink or float? Pure water has a density of 1 g/cm3. Show your work.
For part (a) both Vo and Vo/k was wrong, please help me.
