What rules have to be followed when using the formula v = rw?

Question

Quizplus · Accepted Answer

The formula v = rw involves two variables, v and r, with the same base units (distance) and a third variable, w, which has units of radians. Therefore, choice A is correct. Additionally, since v involves a measure of distance over time, the units for v and r must include time. Therefore, choice B is also correct. Therefore, both choices A and B must be followed when using the formula v = rw.
