A particle of mass 0.400 kilogram is attached to the 100 centimeter mark of a meter stick of mass 0.200 kilogram. The meter stick rotates on a horizontal, frictionless table with an angular speed of 2.00 rad/s.
(a) Estimate the angular momentum of the system when the stick is pivoted about an axis perpendicular to the table through the 30 centimeter mark.
___________ kg•m2/s
A circular pipe has a diameter of 3 cm and then narrows to 2 cm. When water (density= 1000kg/m^3) flows during at a certain rate, the pressure is 32.0 kPa in the larger section, and 24.0 kPa in the smaller section. There is no height change.
