It is important to clarify a common point of confusion for physics students: available for free or public distribution. TIPERS (Tasks Inspired by Physics Education Research) are copyrighted workbooks published by Pearson. Instructors use them as graded assignments, so answer keys are restricted to educator resources.
[ F_{net} = T + mg ] For uniform circular motion (constant speed), the net force must equal the centripetal force: tipers answer key b6
From this equation, solve for tension:
However, I can provide a for the classic B6 question from the TIPERS: Sensemaking Tasks for Introductory Physics (often the Newton’s Laws or Force Analysis section). The B6 question typically involves comparing the net force on an object moving in a vertical circle (like a ball on a string or a roller coaster car at the top of a loop). It is important to clarify a common point
[ T + mg = \frac{mv^2}{r} ]
Where (v) is the speed at the top, (r) is the radius. [ F_{net} = T + mg ] For
