Question

A boomerang has mass m ,surface area a,radius of curvature of lower surface r and it is moving with velocity v in air of density

Answer 1

Answer:

I am assuming that this is your question :

A Boomerang has a mass m, surface Area A, the radius of curvature of lower surface = r and it is moving with the velocity v in air of density ρ. The resistive force on the boomerang should be :

2pv^{2}A/r log {ρAr/πm}
