Kathy dropped a snowball from a building that is 39.2 meters tall. The equation t2 = 39.29.8
represents the amount of time, in seconds, it takes for the snowball to reach the ground. How long did it take the snowball to reach the ground?
A
14
second
B
12
second
C
2 seconds
D
4 seconds
To find the time it takes for the snowball to reach the ground, we need to solve the equation t^2 = 39.2.
Taking the square root of both sides, we get:
t = √39.2
Using a calculator, we find that √39.2 ≈ 6.26.
Therefore, it took the snowball approximately 6.26 seconds to reach the ground.
None of the given options match this answer, so none of the options are correct.
it's one of them
Apologies for the mistake in my previous response.
To find the time it takes for the snowball to reach the ground, we need to solve the equation t^2 = 39.2.
Taking the square root of both sides, we get:
t = √39.2
Using a calculator, we find that √39.2 ≈ 6.26.
Therefore, it took the snowball approximately 6.26 seconds to reach the ground.
Since none of the provided options match this answer, it appears that there may be an error or missing information.
it's B. : 2 seconds
Apologies for the incorrect previous response.
To find the time it takes for the snowball to reach the ground, you need to solve the equation t^2 = 39.2.
Taking the square root of both sides, we get:
t = √39.2
Using a calculator, we find that √39.2 ≈ 6.26.
However, since time cannot be negative, we need to consider the positive value for t. Thus, it takes the snowball approximately 6.26 seconds to reach the ground.
None of the given options match this answer. Therefore, there may be an error or missing information in the question.
To find the time it takes for the snowball to reach the ground, we need to solve for "t" in the equation t^2 = 39.2/9.8.
Taking the square root of both sides, we get:
t = sqrt(39.2/9.8)
Calculating this expression, we find:
t ≈ 2 seconds
Therefore, the correct answer is option C: 2 seconds.
To solve for the time it takes for the snowball to reach the ground, we need to solve the equation t^2 = 39.2/9.8, where t represents time in seconds. We can rearrange the equation to isolate t:
t^2 = 39.2/9.8
Dividing both sides of the equation by 9.8:
t^2/9.8 = 39.2/9.8
Simplifying:
t^2/9.8 = 4
Multiplying both sides of the equation by 9.8 to get rid of the denominator:
t^2 = 4 * 9.8
t^2 = 39.2
Taking the square root of both sides:
t = √(39.2)
Calculating the square root:
t ≈ 6.26
Therefore, it took approximately 6.26 seconds for the snowball to reach the ground.
Given the answer choices, the closest option to 6.26 seconds is 6 seconds, which is not listed. Since none of the given options match the exact answer, it's possible that there is an error in the question or the answer choices provided.
