Projectile motion can be modeled by this quadratic equation, where y represents the height of the object, in feet, and t represents time, in seconds.
y=-16t²+v_0t+h_0
Note that v_0 and h_0 are values representing the object’s initial upward velocity and initial height, respectively. Suppose two science club members have each thrown a tennis ball into the air. The first student throws the ball from a height of 3 feet with an initial upward velocity of 15 feet/second. The second student throws the ball from a height of 4 feet with an initial upward velocity of 35 feet/second. First write a system of equations to represent this situation.
