he figure shows a distance vs. time graph of an object with three distinct regions I, II, and III.   The object’s velocity is positive in region(s)   (picture)   is the answer:   I no region  III II

Can you set up equations with variables for the two cases described?     An example of a situation that I might be able to use an equation with a single unknown would be, suppose I live in a town 100 miles away from my office. How long will it take me to reach my office if I am driving at 75 mph. Time will be unknown, and I am assuming I am driving at a constant speed, so I will apply the following linear equation, Speed = Time Distance → Time = Speed Distance = 1.33hours = 1 hour 20 minutes. Now I'm in the same position as before, but now there are traffic jams, or maybe roadwork, so the speed is not constant, (it varies with time) so in this case speed(time) = time distance → time = speed(time) Distance will therefore fail in this case. In the first case, in the linear case, we can assume that the speed will be constant and independent of other variables, time, which makes the linear method useful in this situation. On the other hand, in our second example, speed is a function of…

Shown is a motion diagram of a car traveling down a street. The camera took one frame every second. A distance scale is provided.a. Use the scale to determine the x-value of the car at each dot. Place your data in a table, similar to Table 2.1, showing each position and the instant of time at which it occurred.b. Make a graph of x versus t, using the data in your table. Because you have data only at certain instants of time, your graph should consist of dots that are not connected together.
