A syringe has a fine needle with an inside diameter of 100 μm. The barrel has a diameter of 2.35 cm and is filled with water. Calculate the velocity of water as it squirts horizontally from the needle if you apply a force of 1.85 N onto the plunger. (Hint: you may approximate the area of the barrel to be much larger than the area of the needle).
