Actually, I'm going to write the units here and make it a little bit. This is meters per second squared. That's going to be our unit for acceleration. This is our unit for velocity. Let's say that we know that the position at time 2, at 2 seconds, is equal to negative 10 meters. If we're thinking in one dimension, if we're just moving along the number line, it's 10 to the left of the origin. Given this information right over here and everything that I wrote up here, can we figure out the actual expressions for velocity as a function of time?
