Two small frogs simultaneously leap straight up from a lily pad. Frog A leaps with an initial velocity of 0.676 m/s, while frog B leaps with an initial velocity of 1.88 m/s. When the first frog to return to the lily pad does so, what is the position and velocity of the other frog? Take upwards to be positive, and let the position of the lily pad be zero.
