Question

The questions in a variety of styles, some of which are meant to help guide you solving techniques, others are formatted more closely to the Concept and Quantitative n questions you encounter on the minitests. There are also unguided, non-multiple that are of a more traditional physics problem" style. Mrs. Pac-Man moves back-and-forth along a straight line. To precisely measure Mrs. Pac-Man's motion in the particle approximation, which of are required? [Enter your answer as a string of the letter options you believe are correct. you think options A, D, and E are correct, then enter "ADE"] You track a single point within Mrs. Pac-Man, moving one dimensionally. Imagine a reference axis, preferably aligned with Mrs. Pac-Man's motion. Choose an origin point along your reference axis. It doesn't have to have a specific pr associated with it. Measure the time it takes for Mrs. Pac-Man to cross the entire reference axis. None of the above.

Explanation / Answer

first we need to decide a reference axis so that all the movement

can be tracked w.r.t. that reference axis.

then we need to assume the origin so that we can assign particular values to the displacement from the origin.

by tracking a single point, we can track the motion along the one dimension axis.

hence option A,B and C are correct
