Tension of a string attached to an instrument inside rocket

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving a rocket landing vertically and the tension in a wire supporting an instrument inside the rocket. The scenario includes the rocket decelerating at a specified rate while the instrument is affected by gravitational forces.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants explore the relationship between the forces acting on the instrument, including tension, gravity, and the rocket's deceleration. There are attempts to clarify the roles of these forces and how they interact.

Discussion Status

The conversation is ongoing, with participants providing guidance on using free body diagrams and discussing the net forces acting on the instrument. There is an emphasis on understanding the signs of forces and accelerations, but no consensus has been reached on the final approach to the problem.

Contextual Notes

Participants express confusion about the signs of forces and accelerations, indicating a need for clarity on these concepts. The original poster mentions an upcoming exam, which may influence their urgency in seeking understanding.

So the total force exerted on the instrument is T, and then mg, the force of gravity. ΣF=T+mg
Good. Now fill in the other side of the ΣF=ma equation.

Wait...

I got it

So I put T-mg=ma, or T-(6)(9.8)=(6)(2.4) and then I got my answer.

Yay ^^
