An earthquake causes a piece of glass to fall off a building from a height of 2,704 ft. If the equation for height as a function of time is h(t) = -16t2 + initial,height where t is time in seconds and h(t) is height in feet, how many seconds will it take for the piece of glass to hit the ground?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![**Problem Statement**
An earthquake causes a piece of glass to fall off a building from a height of 2,704 ft. If the equation for height as a function of time is
\[ h(t) = -16t^2 + \text{initial\_height} \]
where \( t \) is time in seconds and \( h(t) \) is height in feet, how many seconds will it take for the piece of glass to hit the ground?
**Solution**
To solve this problem, we start with the given height equation:
\[ h(t) = -16t^2 + \text{initial\_height} \]
In this specific problem:
- The initial height is 2,704 feet.
So, the height equation is:
\[ h(t) = -16t^2 + 2704 \]
We need to determine the time \( t \) when the piece of glass hits the ground. This occurs when the height \( h(t) \) is 0:
\[ 0 = -16t^2 + 2704 \]
Solving for \( t \):
1. Isolate the \( t^2 \) term:
\[ 16t^2 = 2704 \]
2. Divide both sides by 16:
\[ t^2 = 169 \]
3. Take the square root of both sides:
\[ t = \sqrt{169} \]
\[ t = 13 \]
Therefore, it will take 13 seconds for the piece of glass to hit the ground.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdcee9352-3439-4045-80ac-7707def2f5ae%2F99136a7c-1beb-41be-8a2b-ae79b96a3c35%2Fek3d80j_processed.jpeg&w=3840&q=75)
