Finding Position Function with Initial Position of 5 and v(t) = 5t1/3

In summary, an initial value question is a type of mathematical problem where the value of a variable at a specific starting point, or initial value, needs to be found. To solve this type of question, one must identify the equation or problem, determine the initial value, and use various mathematical methods. Initial value questions are important because they help us understand the behavior of a variable in real-life scenarios. The main difference between an initial value question and a boundary value question is the starting point, and initial value questions usually have a single solution. However, there are some cases where an initial value question may have multiple solutions.

Homework Statement



Find the position function with the given initial position.

v(t) = 5t1/3 s(0)=5

Homework Equations





The Attempt at a Solution



Find the anti derivative

15/4t4/3 + c

s(0) = 15/4t4/3 + c
5 = 0 + c I'm assuming since s(0) = 5 I just substitute 5 for s(0) here
c=5


s(t) = 15/4t4/3 +5

Yes that is correct.
 
  • #3
So if s(1) = 10s(1) = (15/4)(1)^4/3 + c
10 = 15/4 + c
c = 25/4

(just trying to clear up my understanding of these types of problems. thank you for the help.)

Yep.
 

What is an initial value question?

An initial value question is a type of mathematical problem that involves finding the value of a variable at a specific starting point, or initial value. This value is often denoted as "y0" and is used to find the solution to the equation or problem.

How do you solve an initial value question?

To solve an initial value question, you first need to identify the equation or problem and determine the initial value, if given. Then, you can use various mathematical methods such as substitution, integration, or differential equations to find the solution for the variable at the initial value.

Why are initial value questions important?

Initial value questions are important because they allow us to understand the behavior of a variable over time or in a specific situation. They are often used in real-life scenarios to model and predict outcomes in fields such as physics, economics, and engineering.

What is the difference between an initial value question and a boundary value question?

The main difference between an initial value question and a boundary value question is the starting point. In an initial value question, the value at the starting point is given, while in a boundary value question, the values at the boundaries or endpoints are given. Additionally, boundary value questions often involve multiple solutions, while initial value questions typically have a single solution.

Can an initial value question have multiple solutions?

No, an initial value question typically has only one solution. This is because the initial value serves as a starting point and determines the behavior of the variable throughout the problem. However, there are some cases where an initial value question may have multiple solutions, such as in chaotic systems or in nonlinear equations.
