Question

Consider an example of air resistance when the quadratic term is always smaller than the linear term. Let a particle of mass m start from rest and fall feeling air resistance forces:

f_air=-mg((v/v₁) +(v/v₂)²)

Solve for the time required for the particle to reach a velocity of ½ v₁_. Express your answers for part (b) as a fraction of the answer you get for part (a)

a. v₂ goes to infinity, or

b. v₂ = 2v_1,or
