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?

correction

sonstance is constance. my fault

I still dont get what to do. since it has constance vleocity doesnt that mean that it has constant acceleration. what do i look for?

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

the forces acting on it

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

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