How to Read a Syringe

A hypodermic syringe contains a medicine with the density of water (Figure P14.53). The barrel of the syringe has a cross-sectional area A=2.50 ×10^-5 m^2, and the needle has a cross-sectional area a=1.00 ×10^-8 m^2 . In the absence of a force on the plunger, the pressure everywhere is 1 atm. A force 𝐅 of magnitude 2.00 N acts on the plunger, making medicine squirt horizontally from the needle. Determine the speed of the medicine as it leaves the needle's tip. | Numerade
