Homework Help Overview
The discussion revolves around calculating instantaneous acceleration in the context of physics, specifically focusing on the relationship between velocity and acceleration.
Discussion Character
- Exploratory, Conceptual clarification, Mathematical reasoning
Approaches and Questions Raised
- Participants explore the definition of acceleration as the rate of change of velocity and discuss the need for a function to calculate it. Questions arise about the appropriateness of simply subtracting two velocity values and the relevance of calculus in this context.
Discussion Status
Some participants have provided insights into the relationship between velocity and acceleration, while others express uncertainty about the calculus concepts involved. There is an ongoing exploration of how to approach the calculation without reaching a consensus on the method.
Contextual Notes
One participant indicates they are not using calculus-based physics, which may limit the approaches discussed. There is also a mention of a formula for acceleration, but it is presented in a way that encourages independent thought rather than direct application.

Acceleration is the rate of change of velocity.

ok for velocity I got 10.1 m/s and 10.25 m/s ...
so substract them is what you are telling me?

Both are functions of time, so just subtracting them will not be sufficient. Do you know a function for acceleration you can use? You can obtain it by taking the derivative of the function for velocity.

I see, sorry about that.
Here's some information that you can use to solve this problem. I don't want to tell you too much because it is good for you to think about it.
a=(v-vo)/t
where
a=acceleration (m/s2)
v=final velocity (m/s)
vo=initial velocity (m/s)
t=time (s).
