Homework Help Overview

The discussion revolves around the forces acting on a ball bearing moving through motor oil, specifically focusing on the scenario where the ball bearing reaches a constant velocity. Participants are exploring concepts related to forces, friction, and motion in a fluid medium.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are attempting to clarify the meaning of "sonstance" and its implications for the problem. Questions arise about the relationship between constant velocity and acceleration, as well as which forces are acting on the ball bearing.

Discussion Status

The discussion is ongoing, with participants seeking to identify all the forces acting on the ball bearing. Some guidance has been offered regarding the need to consider forces beyond gravity, but no consensus has been reached on the complete set of forces involved.

Contextual Notes

There is some confusion regarding terminology, specifically the term "sonstance," which has been clarified to mean "constant." Participants are also grappling with the implications of constant velocity on acceleration and force balance.

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..?
