A girl rolls a ball up an incline and allows it to return to her. For the angle \(\theta\) and ball involved, the acceleration of the ball along the incline is constant at \(0.25 \mathrm{~g}\), directed down the incline. If the ball is released with a speed of \(4 \mathrm{~m} / \mathrm{s}\), determine the distance \(s\) it moves up the incline before reversing its direction and the total time \(t\) required for the ball to return to the child's hand.
