Calculating Minimum Radius for a Stunt Plane Dive

Click For Summary

Homework Help Overview

The problem involves a stunt pilot who must determine the minimum radius of a circular path while pulling out of a vertical dive, given specific conditions about speed and acceleration limits.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the relationship between acceleration, speed, and radius in circular motion. Some express confusion about the question's requirements and the physical implications of the forces involved during the maneuver.

Discussion Status

The discussion includes attempts to clarify the physics concepts at play, with some participants questioning their understanding of the scenario. There is no clear consensus, but insights into the forces experienced by the pilot are being explored.

Contextual Notes

Participants note the constraints of the problem, including the specified maximum acceleration and the pilot's speed at the lowest point of the circular path.

Homework Statement



A 56.0 {\rm kg} stunt pilot who has been diving her airplane vertically pulls out of the dive by changing her course to a circle in a vertical plane.

Q? If the plane's speed at the lowest point of the circle is 100 {\rm m}/{\rm s}, what should the minimum radius of the circle be in order for the acceleration at this point not to exceed 3.00 g?

Well, what is he relationship between the pilot's acceleration, speed and radius of circular motion?
 
thx 4 tryin but i got the answer thx... i still don't get the question tho...
 
The pilot is diving downwards towards the Earth and then exits the dive by turning into a circle. When the direction of motion is changed she will experience an accelerating force from her seat pushing her upwards. According to N3 she pushes just as hard downwards on the seat, so she will descibe it as sinking into the seat.
