#2A and B
Since #1A is just like both of the graphs in #2, how did you miss it?
#1B is also wrong -- positive acceleration
For the following graphs of position versus time (in one dimension), please determine the acceleration. Need someone to check and see if I selected the correct answers.

For the first graph in the dcP3sjiN link, it looks like it's going over the 0 line so I thought that it meant it is first positive then negative
the slope of the tangent is the velocity.
That slope starts out positive, and then decreases, for negative acceleration.
The actual velocity does not matter -- just its change. Just as shifting the position up or down does not gave any effect on the velocity.
