What is the total distance 4 traveled by the particle?
What is the average acceleration BW of the particle over the first 20.0 seconds?
Express your answer in meters per second per second.
What is the instantaneous acceleration of the par
In principle, you could also just compute and plot the average velocity. The expression for the average velocity is
2BWH<0 0 >
4 0004 0 .
The notation 2BWH<0 0 > emphasizes that this is not an instantaneous velocity
Now that you have reviewed how to plot variables as a function of time, you can use the same technique and draw an acceleration
vs. time graph, that is, the graph of (instantaneous) acceleration as a function of time. As usual in these types of graphs, ti
These examples should show you that the velocity and acceleration can have opposite or similar signs or that one of
them can be zero while the other has either sign. Try hard to think carefully about them as
distinct physical quantitie
