At what time(s) do the rockets have the same velocity? Two toy rockets are traveling in the same direction (taken to be the x axis). A diagram is shown of a time-exposure image where a stroboscope has illuminated the rockets at the uniform time intervals indicated.

In the following questions, you will describe its motion at various points in its fall in terms of its velocity and acceleration. Learning Goal: To understand the distinction between velocity and acceleration with the use of motion diagrams. In common usage, velocity and acceleration both can imply having considerable speed. In physics, they are sharply defined concepts that are not at all synonymous. Distinguishing clearly between them is a prerequisite to understanding motion. Moreover, an easy way to study motion is to draw a motion diagram, in which the position of the object in motion is sketched at several equally spaced instants of time, and these sketches (or snapshots) are combined into one single picture. Part A You drop a power ball on the floor. The motion diagram of the ball is sketched in the figure (Figure 1). Indicate whether the magnitude of the velocity of the ball is increasing, decreasing, or not changing. • View Available Hint(s) O increasing In this problem, we make use of these concepts to study the motion of a power ball. This discussion assumes that we have already agreed on a coordinate system from which to measure the position r (t) (also called the O decreasing O not changing position vector) of objects as a function of time. Let v(t) and a(t) be velocity and acceleration, respectively. Submit Part B Complete previous part(s) Figure C1 of 2 Part C Release Now, consider the motion of the power ball once it bounces upward. Its motion diagram is shown in the figure here (Figure 2). Indicate whether the magnitude of the velocity of the ball is increasing, decreasing, or not changing.
