SUMMARY

The discussion focuses on calculating the required size of a parachute canopy to achieve a landing speed of 10 miles per hour, given a coefficient of aerodynamic drag of 1.45. The problem specifies that the parachute is circular and descends vertically without gliding. Participants noted that existing equations for parachute dynamics typically include mass as a variable, leading to uncertainty about how to approach the problem without it. The conclusion emphasizes the need for a method to derive the canopy size without directly incorporating mass.

PREREQUISITES
  • Understanding of aerodynamic drag coefficients
  • Familiarity with circular parachute design principles
  • Basic knowledge of kinematics and descent dynamics
  • Ability to manipulate and solve algebraic equations
NEXT STEPS
  • Research the relationship between parachute area and descent speed
  • Explore the physics of drag forces in free fall
  • Study the derivation of parachute equations without mass dependency
  • Learn about the impact of different drag coefficients on parachute performance
USEFUL FOR

Aerospace engineers, physics students, and anyone involved in parachute design or studying the dynamics of free fall will benefit from this discussion.

Homework Statement


Parachutists open the canopy of their parachutes in order to reduce the speed at which
they land on Earth. How large should a parachute canopy be in order to reduce the
landing speed to 10 miles per hour? Consider the parachute to be circular, to be
descending vertically without gliding, and to have a coefficient of aerodynamic drag of
1.45


Homework Equations


problem is all equations i find include mass as a variable.


The Attempt at a Solution


none.
 
Physics news on Phys.org
Perhaps the mass will cancel out somewhere in the solution...?
