2 tusaale oo ku saabsan ku dhaqanka sharciyada Newton ee diyaarad siman (aan lahayn is jiidjiid)
1. Cufka baloogga waa 2 kg, dardargelinta cufisjiidadka awgeed = 10 m/s2Go'aami (a) xoogga ka dhasha ee dardargeliya baloogga (b) baaxadda dardargelinta baloogga.
Dood
Waa la garanayaa :
Cufka baloogga (m) = 2 kg
Dardargelinta cufisjiidadka awgeed (g) = 10 m/s2
Miisaanka baloogga (w) = mg = (2)(10) = 20 Newton
wx = w sin 30 = (20)(0,5) = 10 Newtons
wy = w cos 30 = (20)(0,5√3) = 10√3 Newtons
Jawaab:
(A) xoogga ka dhasha ee dardargeliya xannibaadda
Diyaarad siman oo is jiidjiid ah oo loo malaynayo inay maqan tahay. Sidaa darteed, xoogga saameeya dhaqdhaqaaqa baloogga waa kaliya wx
(B) baaxadda dardargelinta baloogga
Baaxadda xawaaraha baloogga waa 5 m/s2, jihada dardargelinta baloogga ayaa hoos u socota.
2. Balooggu wuxuu ku yaal meel siman oo aan is jiidjiid lahayn. Cufka baloogga waa 3 kg, dardargelinta cufisjiidadka awgeedna waa 10 m/s.2. Go'aami baaxadda xoogga F haddii (a) balooggu wali yahay (b) balooggu uu hoos ugu socdo xawaare dhan 2 m/s2 (c) balooggu wuxuu kor u socdaa iyadoo xawaare joogto ah oo ah 2 m/s2.

Waa la garanayaa :
Cufka baloogga (m) = 3 kg
Dardargelinta cufisjiidadka awgeed (g) = 10 m/s2
Miisaanka baloogga (w) = mg = (3)(10) = 30 Newton
wx = w sin 30 = (30)(0,5) = 15 Newtons
wy = w cos 30 = (30)(0,5√3) = 15√3Newtons
Jawaab:
(a) Go'aami F haddii balooggu nasto.
Sharciga ugu horreeya ee Newton wuxuu dhigayaa in shay uu nasto haddii xoogga ka dhasha uu eber yahay.
(b) Go'aami F haddii balooggu hoos u socdo iyadoo xawaareyntiisu tahay 2 m/s2
(c) Go'aami F haddii balooggu kor u kaco iyadoo xawaare joogto ah uu yahay 2 m/s2
