H.W: A hypodermic syringe contains a medicine with the density of water. The barrel of the syringe has a cross-sectional area (2.50x10-5) m2, and the needle has a cross-sectional area (1.00x10 8 ) m². In the absence of a force on the plunger, the pressure everywhere is 1.00 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 needles tip.
