Calculating Stone Distance and Speed: Kinematics Problem Help

Click For Summary

Homework Help Overview

The problem involves kinematics, specifically the motion of two stones dropped from a height, with a focus on their distances apart when the second stone reaches a certain speed.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss calculating the displacement of the first stone and how to relate it to the second stone's motion. There are questions about the setup of the problem and the necessary calculations to find the second stone's displacement.

Discussion Status

Some participants are attempting to calculate the displacement of the stones at a specific moment, while others are seeking clarification on the steps needed to find the second stone's displacement. There is an emphasis on showing work to facilitate further discussion.

Contextual Notes

Participants are navigating the timing of the drops and the relationship between the speeds and displacements of the stones, with some uncertainty about the calculations involved.

Homework Statement



A stone is dropped from the roof of a high building. A second stone is dropped 1.50 s later. How far apart are the stones when the second one has reached a speed of 11.0 m/s?

Homework Equations

The Attempt at a Solution



i need help setting up the problem i don't know how

Well, work out the displacement of the first stone when it reaches 11m/s, then the displacement of the second stone at this time.
 
i got the displacement of the first one as 6.17 m how do i get the second one?
 
There's no way I can tell you you're right or not if I don't see your work! Try calculating the time when the stone reaches 11m/s. Then you can perhaps find the displacement of the second stone at this time.
