I got a graph with time on the x-axis, and distance on the y-axis. (see attached picture)
I have to calculate the acceleration using only the distance – time graph.
2. Relevant equations
I used S(t)=S(0) + V(0) * t + .5 * a * t2
3. The attempt at a solution
That gives 1.30=0+0*3.09 + .5 * a * 3.092
But I know the acceleration is 0.42171 m/s2, because that’s the slope of the V,t graph. What am I doing wrong here?
