Answer:
0.032
Step-by-step explanation:
The drag force is described as the force experienced by an object due to movement through a liquid. In this case it is water. The equation used for drag force F is:
[tex]F=0.5pu^2[/tex]
the density of water is p=1000 kg/m³. We know that F=0.5 N.
[tex]0.5=0.5\cdot{1000}u^2[/tex]
[tex]u=\sqrt{0.001}[/tex]
[tex]u=0.031[/tex]
The speed is 0.032 m/s
