Mehlala e 'meli ea ho sebelisa melao ea Newton sebakeng se boreleli se sekametseng (ha ho khohlano)

1. Boima ba boloko ke 2 kg, ho potlaka ka lebaka la matla a khoheli = 10 m/s²Fumana (a) matla a hlahang a potlakisang boloko (b) boholo ba lebelo la boloko.
Puisano
Hoa tsebahala :
Boima ba boloko (m) = 2 kg
Ho potlaka ka lebaka la matla a khoheli (g) = 10 m/s²
Boima ba boloko (w) = mg = (2)(10) = 20 Newton
w_x = w sebe 30 = (20)(0,5) = 10 Newton
w_y = w cos 30 = (20)(0,5√3) = 10√3 Li-Newton
Karabo:
(A) matla a hlahang a potlakisang thibelo
Sefofane se sekametseng hantle moo ho nahanoang hore khohlano ha e eo. Ka hona, matla a amang motsamao oa boloko ke feela_x
(B) ho potlakisa ho hoholo ha boloko
Boholo ba lebelo la boloko ke 5 m/s², tataiso ea ho potlaka ha boloko e theohela tlase.

2. Boloko bo sebakeng se boreleli, se sekametseng ntle le ho hohlana. Boima ba boloko ke 3 kg, mme lebelo le bakwang ke matla a khoheli ke 10 m/s.²Fumana boholo ba matla F haeba (a) boloko bo ntse bo le teng (b) boloko bo theohela tlase ka lebelo la 2 m/s² (c) boloko bo nyolohela hodimo ka lebelo le sa fetoheng la 2 m/s².

Karabo:
(a) Fumana F haeba boloko bo phomotse.
Molao oa pele oa Newton o bolela hore ntho e phomotse haeba matla a hlahang e le lefela.
(b) Fumana F haeba boloko e theohela tlase ka lebelo la 2 m/s²
(c) Fumana F haeba boloko e nyolohela hodimo ka lebelo le sa fetoheng la 2 m/s²
