A ball thrown straight upward from a height of 5 ft with an initial velocity of 50 ft per sec has height h(t) feet after t seconds, where h(t) =- 16t + 50t + 5. What is the ball's average velocity (that is, its average rate of change in height) during the first second? The average velocity during the first second is (Type an integer or a simplified fraction.) feet per second.
Optimization
Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the selection of the best element for a given system.
Integration
Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integration and differentiation are inverse operators. Differential equations give a relation between a function and its derivative.
Application of Integration
In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.
Volume
In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects that have length, breadth, and height (or depth).
Area
Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
![**Problem Overview:**
A ball thrown straight upward from a height of 5 ft with an initial velocity of 50 ft per sec has height \( h(t) \) feet after \( t \) seconds, where \( h(t) = -16t^2 + 50t + 5 \). What is the ball's average velocity (that is, its average rate of change in height) during the first second?
**Solution:**
The average velocity during the first second is \(\underline{\hspace{2cm}}\) feet per second.
*(Type an integer or a simplified fraction.)*

**Explanation:**
To calculate the ball's average velocity during the first second, use the formula for average velocity over an interval \([a, b]\):
\[ \text{Average Velocity} = \frac{h(b) - h(a)}{b - a} \]
Here, we need to find the average velocity from \(t = 0\) to \(t = 1\).
1. **Calculate \( h(0) \):**
\[ h(0) = -16(0)^2 + 50(0) + 5 = 5 \]
2. **Calculate \( h(1) \):**
\[ h(1) = -16(1)^2 + 50(1) + 5 = -16 + 50 + 5 = 39 \]
3. **Average Velocity:**
\[ \text{Average Velocity} = \frac{h(1) - h(0)}{1 - 0} = \frac{39 - 5}{1} = 34 \]
So, the average velocity during the first second is 34 feet per second.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff537747e-0d69-4ed8-ad12-350a5c79286a%2F669ba30f-d496-44c2-a32b-db6d350e82ad%2F8s8ax3_processed.jpeg&w=3840&q=75)
