Homework Help Overview

The problem involves calculating angular velocity and the force exerted on a table by a rotating mass. It is situated within the context of circular motion and dynamics.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the calculation of angular velocity based on given parameters and explore the subsequent force on the table related to the mass's rotation.

Discussion Status

The discussion has progressed with some participants confirming the correctness of the angular velocity calculation for part (a). However, part (b) remains open for exploration, with participants seeking further insights.

Contextual Notes

Participants are working with specific values for mass and rotation speed, but there may be additional assumptions or information needed to fully address part (b).

Hi guys. I need some help to solve this question.

(a) A body of mass m kg is attached to a point by string of length
1.25 m. If the mass is rotating in a horizontal circle 0.75 m below the
point of attachment, calculate its angular velocity.

(b) If the mass rotates on a table, calculate the force on the table when
the speed of rotation is 25 rpm and the mass is 6 kg.

Hi bahramm,

Show us what you've done.
 


I got w^=g/h w=3.61 so far correct?
 


Yes that's the answer for part a.
 


cool. any idea about part b?
