Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.

Determine the√?−????numerical values of ? for an object moving at speed ? =0.01?, 0.05?, 0.10?, 0.20?, 0.30?, 0.40? 0.50?, 0.60?, 0.70?, 0.80?, 0.90?, 0.99?. Make a graph of? ?????? ?.
For part b, I do not really understand what the question is asking. During the 200 m trip upwards, to we have to consider that the elevator accelerates for 5 seconds, then decelarates for 5 secs and then moves with constant velocity? I do get the final answer that is 45 secs, but Ido not conceptually understand how I am supposed to understand that there is a period of decelaration during the upward motion. Could you please solve only part b and help me understand why both periods of acceleration and deceleration both need to be taken into consideration?

I need help answering and explaning this physics FRQ: Two identical objects, A and B, move along straight, parallel, horizontal tracks. The graph attached as the image represents the position as a function of time for the two objects. (a) At approximately which time or times, if any, are the objects moving at the same speed? If the objects are never moving with the same speed during the interval shown, indicate this explicitly. Briefly explain your answer. (b) Describe what is happening to the positions of objects A and B between 3 seconds and 4 seconds. (c) Which object, if either, has an acceleration with a greater magnitude during the time interval shown in the graph? If the accelerations have the same magnitude for both objects, indicate this explicitly. (d) In a clear, coherent, paragraph-length response, explain your response to part (c). Be sure to reference and compare the graph information for both objects A and B.
