AI Thread Summary
The discussion focuses on calculating the frictional force acting on a ball bearing moving through motor oil at a constant velocity of 4.5 cm/s. Participants clarify that "sonstance" refers to "constant," indicating that the ball bearing experiences no acceleration. The main forces acting on the ball bearing include gravity and the frictional force from the oil, which balances the gravitational force when the bearing reaches constant velocity. Understanding these forces is essential for calculating the frictional force. The conversation emphasizes the importance of identifying all forces to solve the problem effectively.

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 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?
 
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..?
