At the local playground, a child on a swing has a speed of 2.12 m/s when the swing is at its lowest point.
Part A: To what maximum vertical height does the child rise, assuming he sits still and "coasts"? Ignore air resistance.
Part B: How do your results change if the initial speed of the child is halved?

At the local playground, a 21-kg child sits on the right end of a horizontal teeter-totter, 1.8 m from the pivot point. On the left side of the pivot an adult pushes straight down on the teeter-totter with a force of 151 N. Part A In which direction does the teeter-totter rotate if the adult applies the force at a distance of 3.0 m from the pivot? (clockwise/ counterclockwise) Part B In which direction does the teeter-totter rotate if the...
