22. Two students are working on the same constant-acceleration problem involving a car undergoing constant
acceleration, having started from rest and after a certain time having traveled a distance of 108 m. The students are to find
the average velocity. Both students are required to show their work and round any intermediate answers as well as the
final answer properly to 3 significant figures. Each rounded answer is to be used in the next step of calculation as they
proceed. For the final answer, Student A uses the formula vavg = (xf – xi)/(tf – ti) getting the result 7.26 m/s, and Student B
uses the formula vavg = (v0 + v)/2 getting the result 7.29 m/s. Assuming neither student makes a mistake, which student
