First remember the following kinematic equations:
 a = g
 vf = g * t + vo
 rf = (1/2) * g * t ^ 2 + vo * t + ro
 g: gravity
 t: time
 vf: final speed
 Vo: initial speed
 For this case what we should do is to choose the equation that best suits each statement.
 We have then:
 GroupA: h (t) = - 4.9 * t ^ 2 + 19 * t
 Group B: h (t) = - 16 * t ^ 2 + 50 * t
 Group C: h (t) = - 4.9 * t ^ 2 +19
 Group D: h (t) = - 16 * t ^ 2 +50

(x^2+5x-36)/(x^2-16)
=(x^2+9x-4x-36)/(x^2-4^2)
=x(x+9)-4(x+9)/(x+4)(x-4)
=(x-4)(x+9)/(x+4)(x-4)
=x+9/x+4
