What Forces Act on a Ball Bearing Moving Through Oil?

[soulja101]

A small ball bearing having a mass of 50.0g was dropped in a graduated cylinder filled with a thick but clear motor oil. At the point shown by the diagram, this ball bearing was moving at a sonstance velocity of 4.5cm/s.Use This information to calulate the frictional force of the oil on the ball bearing.

I have no idea how to start it .

Does sonstance mean constant??

If so, if it means that, what force is the friction force balancing?

 

[soulja101]

correction

sonstance is constance. my fault

 

[soulja101]

I still don't get what to do. since it has constance vleocity doesn't that mean that it has constant acceleration. what do i look for?

 

[Vesper89]

It means it has no acceleration...try figuring out all the forces that are acting on the ball and work from there.

 

[soulja101]

the forces acting on it

the only forces i think are acting on it are gravity.

 

[arildno]

Yes, gravity works on it, in addition to the..?
