At the local playground, a 21-kg child sits on the right end ofa horizontal teeter-totter, 1.8 m from the pivot point. On the leftside of the pivot an adult pushes straight down on the teeter-totterwith a force of 151 N. In which direction (clockwise or counterclockwise) does the teeter-totter rotate if the adult applies the forceat a distance of (a) 3.0 m, (b) 2.5 m, or (c) 2.0 m from the pivot?

Question

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. In which direction (clockwise or counterclockwise) does the teeter-totter rotate if the adult applies the force
at a distance of (a) 3.0 m, (b) 2.5 m, or (c) 2.0 m from the pivot?
