1. Homework Statement
The velocity of a particle moving along the x-axis varies in time according to the expression
v(t)=α+βt2
α=46.4m/s
β=4.25m/s3
t is in seconds
Find the average acceleration in the time interval from t=0 to 3.63s.
Answer in units of m/s2
2. Homework Equations
I really do not have the slightest idea as to what equation to use for this. I know I need to find the average acceleration which is a=Δv/Δt, however, I don't recognize how to get the initial and final velocities out of that problem. It's already given me the initial time and final time so obviously 3.63s-0s=3.63s but as previously stated, how do I pull the initial and finals out of that? (Even if that is the way to go about it.) I have tried a few things and my results of those will be under this.
3. The Attempt at a Solution
First I got 28.20986915 just by plugging and chugging. I'm still working on it but I am in desperate need of a quick lesson on how to solve this problem and the concepts of it.
Please, no answers; I only want to know and understand how to solve this.
Thank you.
