I did my best to keep the line dotted properly.
Answer:
The correct option is b: 6 seconds.
Step-by-step explanation:
The formula is:
Where:
t: is the time
h: is the height = 384 ft
When the stone hit the ground, h = 0
To solve the above quadratic equation we need to use the following formula:
(1)
Where:
a: is the coefficient of t² = -16
b: is the coefficient of t = 32
c: is the independent term = 384
By entering the above values into equation (1) we have:
Since we can not take the negative value of time (t₂) equal to -4, the answer is 6 seconds.
Therefore, the stone will hit the ground in 6 seconds. The correct option is b: 6 seconds.
I hope it helps you!
