Laura and Kennedy are at softball practice. Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second. Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second. If x is the time, y is the height of the ball, and the acceleration due to gravity is -32 feet per square second, which system of equations models the projectile motion of the two balls?
