A straight ditch is 100m long and has the cross-section of a semi-circle of radius 1m. The ditch is full of water (density 103kg/m3 ) and we wish to calculate how much work is required to empty the ditch by pumping all the water to the top of the ditch where it can flow out through an overflow pipe. You should take the acceleration due to gravity to be g = 9.8m/s2 . (a) Draw a sketch of the ditch...

Consider the track shown in the Figure. The section AB is one
quadrant of a circle of radius 2.0m and is frictionless. B to C is
a horizontal span 3.0m long with a coefficient of kinetic friction
μk = 0.25. The section CD under the spring is frictionless. A block
of mass 1.0kg is released from rest at A. After sliding on the
track, it compresses the spring by 0.20m. Use g=10m/s2.

A trough is 7 meters long. 1.5 meters wide and 5 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 5 meters, and base, on top, of length 1.5 meters). The trough is full of water :). Find the amount of work in joules m3 required to empty the trough by pumping the water over the top. (Note: Use g = 9.8% as the acceleration due to gravity.) (density...
