1. Koloi ea boima ba lik'hilograma tse 2000 e potoloha mothinya tseleng e bataletseng ea radius ea 150 m. Coefficient ea khohlano e sa fetoheng ke 0.5. Fumana lebelo le phahameng ka ho fetisisa e le hore koloi e latele mothinya 'me e se ke ea thella. Ho potlaka ka lebaka la matla a khoheli = 10 m/s 2.
Tse tsejoang:
Boima (m) = 2000 kg
Radius (r) = limithara tse 150
Koefficient ea khohlano e sa fetoheng ( μs ) = 0.5
Boima (w) = mg = (2000 kg)(10 m/s 2 ) = 20,000 kg m/s 2 = 20,000 N
Matla a khohlano e tsitsitseng (F s ) = μ s N = μ s w = (0.7) (20,000 N) = 14,000 N
