Determine how much work should you do to push a block of steel of 14.29 kg across a steel table at a steady speed of 1.09 m/s for 3.69 s? (The Coefficient of kinetic friction is equivalent to k = 0.68.)
If the similar block is then placed in an unknown liquid, unattached to a scale, it floats with 2/3 of its volume submerged in the unknown fluid. The density of water is around 1.00 × 103 kg/m3. Find out the density of the unknown liquid.
