A circular cylinder of height 1.20 m having faces of diameter 0.620 m is immersed in water of density 1.00 × 103 kg/m3 with its axis vertical so that its faces are parallel to the surface of the water
The upper face is 2.50 m below the surface of the water. The net force on this cylinder is observed to be 1120 N downward. Atmospheric pressure is 1.01 × 105 Pa. What net force does the water exert on the lower face of the cylinder?
A) 7.40 × 103 N
B) 1.09 × 104 N
C) 3.79 × 104 N
D) 4.14 × 104 N
E) 1.37 × 105 N

A block is projected with speed v across a horizontal surface and slides to a stop due to friction. The same block is then projected with the same speed v up an incline where it slides to a stop due to friction. In which case did the total mechanical energy of the block decrease the least?
a. This problem cannot be solved since it was not indicated whether the horizontal surface and the incline both had the same coefficient of kinetic friction. b. The case on the horizontal surface had the least decrease in total mechanical energy. c. The case on the inclined surface had the least decrease in total mechanical energy. d. In both cases the decrease in mechanical energy was the same.
