A basic kinematics problem that I just can't get for some reason. I'm having trouble visualizing the graph. 1. The problem statement, all variables and given/known data What's the average acceleration if a car's going 12 m/s constant speed, then accelerates for 12 seconds at 1.7 m/s^2 acceleration? Variables: none? 2. Relevant equations ? I do not know. At all. 3. The attempt at a solution I had graphed speed over time with the function as a horizontal line until it reached the origin, where it gained a slope of 1.7 because of the acceleration. I don't know if I'm visualizing the increase in speed correctly or if it would become an exponential curve. If this was the result, I don't know how I would then find average speed--total distance over time. Would I need to know calculus to figure this out? So this is where I'm stuck.
