A projectile of mass \(m\) is launched from flat, horizontal ground with an initial speed \(v_0\) at an angle \(\theta_0\) above the horizontal, where \(0^\circ < \theta_0 < 90^\circ\). The projectile reaches a maximum height \(H\) at time \(t_{\text{top}}\) and returns to the ground at time \(2t_{\text{top}}\). Air resistance is negligible, and the kinetic energy of the projectile is given by \(K = \dfrac{1}{2}mv^2\). Which of the following pairs of graphs best represents the projectile's kinetic energy \(K\) as a function of height \(y\) and as a function of time \(t\) throughout its flight?
