A. The free term represent the height of the window, on the second floor
B.  -16t²-8t+24=-8(2t²+t-3)= - 8(2t+3)(t-1)
C. - 8(2t+3)(t-1)=0
2t+3=0, 2t=-3, t1=-3/2
t-1=0, t2=1
D. t1 (I think) represents  the time before the paper ball reached the window, when Jacob only began to threw the the ball,
t2 represent the time when ball passes the window , and the height of the ball was the same as the height of the Jacob hand that was trowing the ball (while he is on the second floor)
