A hypodermic syringe contains a medicine with the density of water (1,000 kg/m). The
barrel of the syringe has a cross-sectional of 2.50 x 10 m and the needle has a
cross-sectional area of 1.00×10 m. In the absence of a force on the plunger, the
pressure everywhere is 1.00 atm (760 mmHg). A force of magnitude 2.00 N acts on the
plunger, making the medicine squirt horizontally from the needle. Determine the speed of
the medicine as it leaves the needle's tip
