My question deals with times of flight under a linear model of air resistance. Let me describe the problem.(adsbygoogle = window.adsbygoogle || []).push({});

Up problem: v' = -g - kv, x(0) = 0, v(0) = v_0

Down problem: v' = -g + kv, x(0) = h, v(0) = 0

Define T_{up} and h (max. height) by the Up problem: x(T_{up}) = h, v(T_{up}) = 0

Define T_{down} by Down problem: x(T_{down}) = 0

Question: Does T_{down} = T_{up}? (prove/disprove)
