Question

Determine the initial height of the ball and the time interval before the ball hits the ground. initial height = 0; hits the ground between 5 and 6 seconds initial height = 150; hits the ground between 5 and 6 seconds initial height = 0; hits the ground between 3 and 4 seconds initial height = 150; hits the ground between 4 and 5 seconds

Answer 1

Initial height = 150; hits the ground between 5 and 6 seconds

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

Answer 2

Answer: B) initial height = 150; hits the ground between 5 and 6 seconds
