Question

A steel ball is traveling through water with a speed of x meters per second, where x is positive the drag force, F

At what speed in meters per second does the ball have a force of 0.5 N on it

Answer 1

0.032

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:

`F=0.5pu^2`

the density of water is p=1000 kg/m³. We know that F=0.5 N.

`0.5=0.5\cdot{1000}u^2`

`u=√(0.001)`

`u=0.031`

The speed is 0.032 m/s
