To learn to use images of an object in motion to determine position, velocity, and acceleration.
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. ()
A) At what time(s) do the rockets have the same velocity?
B) At what time(s) do the rockets have the same x position?
C) At what time(s) do the two rockets have the same acceleration?
D) The motion of the rocket labeled A is an example of motion with uniform (i.e., constant) __________.
E) The motion of the rocket labeled B is an example of motion with uniform (i.e., constant) __________.
F) At what time(s) is rocket A ahead of rocket B?
at some instant in time between t=1 and t=4
at times t=1 and t=4
at no time shown in the figure
and nonzero acceleration
before t=1 and after t=4
