Homework Help Overview

The problem involves a meter stick with a specified mass and length, pivoted at one end, and released from a horizontal position to swing through a vertical orientation. The objective is to calculate the linear speed of the end of the stick as it swings down and to find the ratio of this speed to that of a particle falling a certain distance.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the calculation of linear speed at the end of the swinging stick and the subsequent ratio to the speed of a falling particle. There is a request for clarification on the approach to part D, particularly regarding the interpretation of the ratio.

Discussion Status

The discussion includes attempts to calculate the speed for part C, with one participant providing a specific value. However, there is a lack of clarity regarding part D, leading to a request for further assistance. One participant acknowledges a misunderstanding of the problem statement.

Contextual Notes

Participants are working under the constraints of a homework assignment, which may limit the information they can provide or seek. There is an emphasis on understanding the relationship between the speeds being compared.

A stick with a mass of 0.152 kg and a length of 1.00 m is pivoted about one end so it can rotate without friction about a horizontal axis. The meter stick is held in a horizontal position and released.
C-As it swings through the vertical, calculate the linear speed of the end of the stick opposite the axis.
D-Find the ratio of the speed of a particle that has fallen a distance of 1.00 m, starting from rest, to the speed from part (C).
For part C I got 5.42 m/s I just cannot figure out part d. Any help would be greatly appreciated!

Welcome to the PF.

Please show us your work for how you got part (C).
 
v=rw= (1 m)(5.42 rad/s)=5.42 m/s
 
Never mind I didn't read the problem correct. I didn't realize it said ratio :)
Thanks anyway!
