Homework Help Overview

The problem involves finding the position function given a velocity function v(t) = 5t^(1/3) and an initial position of s(0) = 5. Participants are exploring the relationship between the position and velocity functions through integration.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss finding the antiderivative of the velocity function to derive the position function. There is an attempt to clarify the integration process and the application of initial conditions.

Discussion Status

Some participants confirm the correctness of the initial steps taken in finding the position function. Others express a desire to deepen their understanding of the problem type and the implications of the initial conditions.

Contextual Notes

There appears to be some confusion regarding the constants involved in the position function, particularly when substituting values to find c. Participants are working within the constraints of the problem as posed, focusing on the integration and initial condition application.

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.
 
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.
