Example 2: Calculating Time from Power A typical healthy adult human can provide 150 W of output power. You have
to push a 65 kg box of cereal (at rest) along the floor, and the coefficient of
friction with the floor is 0.37 (your shoes have a coefficient of friction of 0.84
with the floor). How much time should it take you to push it 3 m along the
floor at maximum power? Assume you push at constant speed after initially
starting to move it.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
