Tara and mallory are practicing their passing at volleyball practice. tara bumps the ball from a height of 3.25 feet above the ground with and initial upward velocity of 9 feet/second. if x represents the number of seconds since each ball is passed and y represents the height of the ball, which system of equations models the projectile motion of the two balls? recall that the acceleration due to gravity is -32 feet/second

y=?
y=?
