1. The problem statement, all variables and given/known data I am trying to develop simulation for a falling object subject to air resistance. Object is similar to Samara seed. object is considered to be under steady vertical descend. know variable : surface area of object (A) weight of object (W) cd: drag coefficient object rotates while falling. length from center of rotation to tip of the object (L) inclines at an angle beta (β) Swept disk radius (r) = L*cos(β) 2. Relevant equations terminal velocity(Vs)= √[(2*W)/(cd*ρ*A) Disk loading= W/A=ρ(Vs2-Vf2)/2 3. The attempt at a solution I am stuck in this position and don't know how to approach the problem from here. want to know how to calculate the velocity of object and angular velocity of the tip of the object.
