Chapter 8: Problem 84
At the local playground, a 16-kg child sits on the end of a horizontal teeter- totter, \(1.5 \mathrm{~m}\) from the pivot point. On the other side of the pivot an adult pushes straight down on the teeter-totter with a force of \(95 \mathrm{~N}\). In which direction does the teeter-totter rotate if the adult applies the force at a distance of (a) \(3.0 \mathrm{~m}\), (b) \(2.5 \mathrm{~m}\), or (c) \(2.0 \mathrm{~m}\) from the pivot? (Assume that the teeter-totter itself pivots at the center and produces zero torque.)
