Object A is dropped from a height of $H$ feet, and its height above the ground is modeled by $h_A(t)=-16t^2+H$. Object B is dropped from a height of $4H$ feet, and its height above the ground is modeled by $h_B(t)=-16t^2+4H$. If Object A takes $T$ seconds to hit the ground, how many seconds will Object B take to hit the ground, in terms of $T$?
