Find the average speed from t = 0 to t = 1 s

[valerieangel]

Homework Statement

The position of a particle as a function of time is given by x = (6 m/s)t + (-2 m/s^2)t^2.

Find the average speed from t = 0 to t = 1 s

---------------------------------------------------------------------------------------Also, how would I plot x versus t for t = 0 to t = 2 s?

Homework Equations

average speed = ΔV/Δt

Part A: t=1s

The Attempt at a Solution

I have not a clue.

1) Average speed is Δx/Δt
- Consider evaluating the position function both at t= 1s and t = 0s to be able to calculate Avg Speed
2) If you struggle with plotting points on a graph, try starting with an x/y chart
For instance:
t (s) x(t)
0 6(0) - 2(0)^2
and in general:
t 6t - 2t^2

Take these points and plot them as (t, x(t)), with t as the x-axis and x(t) as the y-axis.
