Answer:
Initial height = 150; hits the ground between 5 and 6 seconds
Step-by-step explanation:
The table for this problem is:
t y
0 150
1 145.1
2 130.4
3 105.9
4 71.6
5 27.5
6 -26.4
So, from the table we observe that the initial height is 150, and the ball hits the ground between 5 and 6 seconds.
The initial height is when the time is zero, because at this point, the movement is going to initiate.
The ball hits the ground between 5 and 6 seconds, because you can see that inside that interval the height change from positive to negative, where zero is the ground level, and the zero is between 27.5 and -26.4.
Therefore the answer is initial height = 150; hits the ground between 5 and 6 seconds
