Do all parts for C and answer the following questions.
1. In general, how do you get the initial velocity from a vx(t) graph that is linear?
2. In general, what does the slope of a vx(t) graph tell you and what are its units if velocity is in
m/s and time is in s?
3. If you only know that an object has a positive acceleration (and you know nothing else), can you
say whether it is speeding up or slowing down?
4. If you only know that an object has a negative acceleration (and you know nothing else), can you
say whether it is speeding up or slowing down?
5. If you are told whether the initial velocity is positive or negative and if you are told whether
the acceleration is positive or negative, how can you know whether the object is speeding up or
slowing down?
