Question

A veterinarian uses a hypodermic syringe like the one shown in the figure to inject a horse with a medical solution with a density that is the same as water. The barrel of the syringe has a cross-sectional area of 2.53  10^-5 m² and before she exerts any force on the plunger, the pressure everywhere in the syringe is 1.00 atm. When she exerts a force with a magnitude of 2.55 N on the plunger, the medical solution squirts horizontally from the needle. Determine the speed of the solution as it leaves the needle.
m/s
