Wow, my physics book is harsh:
"A 90-kg weakling cannot do even one pull-up. By standing on a scale (Fig. 12-3), he can determine how close he gets. His best effort results in a scale reading of 23 kg. What force is he exerting? Solution: There are three forces acting on our non-athlete, as show in Fig. 12-3:..."
That's almost as bad as the one from a few chapters ago:
"An airplane pilot fell 370 m after jumping without his parachute opening. He landed in a snowbank, creating a crater 1.1 m deep, and died on impact. Assuming the pilot's mass was 80 kg, and his terminal velocity was 50 m/s, estimate: (a) the work done by the snow in bringing him to rest; (b) the average force exerted on him by the snow to stop him; and (c) the work done on him by air resistance as he fell."
Ok ok, it actually said "...1.1 m deep, but survived with minor injuries". But I like my way better... because then his velocity was most certainly... terminal.
