Dhaqdhaqaaqa diyaaradda janjeerta iyada oo aan lahayn xoogga is-jiidjiidka - hirgelinta sharciga Newton ee dhibaatooyinka dhaqdhaqaaqa iyo xalalka

1. Cufka sanduuqa = 2 kg, dardargelinta cuf-isjiidadka awgeed = 9.8 m/s ^{2. Soo hel (a) xoogga saafiga ah ee dedejiya sanduuqa hoos u dhigista (b) baaxadda} dardargelinta sanduuqa.

Solution

La yaqaan:

Cufnaanta (m) = 2 kg

Dardargelinta cufisjiidadka awgeed (g) = 9.8 m/s ²

Miisaanka (w) = mg = (2)(9.8) = 19.6 Newtons

w _x = w sin 30 = (19.6)(0.5) = 9.8 Newtons

w _y = w cos 30 = (19.6)(0.5√3) = 9.8√3 Newtons

Xalka:

(a) Shabaqa ce ee dardargeliya sanduuqa

Diyaaradda leexatay waa siman tahay, sidaa darteed ma jirto xoog is jiidjiid ah. Xoogga kaliya ee ku shaqeeya shayga waa w _x.

∑ F = w _x

∑ F = 9.8 Newton

(b) baaxadda dardargelinta

∑ F = ma

9.8 = (2) a

a = 9.8/2

a = 4.9 m/s ²

Baaxadda xawaaraha waa 4.9 m/s ² , jihada xawaaraha ayaa hoos u socota.

2. Diyaaradda leexatay waa siman tahay sidaa darteed ma jirto xoog is jiidjiid ah . Cufnaanta shayga waa 3 kg, dardargelinta cufisjiidadka awgeed waa 9.8 m/s ^2. Go'aami baaxadda xoogga F haddii (a) shaygu nasto (b) shaygu uu hoos u socdo iyadoo la adeegsanayo dardargelin joogto ah oo ah 2 m/s ² (c) shaygu uu kor u socdo iyadoo la adeegsanayo dardargelin joogto ah oo ah 2 m/s ².

Solution

La yaqaan:

Cufnaanta (m) = 3 kg

Dardargelinta cufisjiidadka awgeed (g) = 9.8 m/s ²

Miisaanka (w) = mg = (3)(9.8) = 29.4 Newtons

w _x = w sin 30 = (29.4)(0.5) = 14.7 Newtons

w _y = w cos 30 = (29.4)(0.5√3) = 14.7√3 Newtons

Xalka:

(a) Baaxadda xoogga F haddii shay uu nasto

Sharciga ugu horreeya ee dhaqdhaqaaqa Newton wuxuu dhigayaa in haddii shay uu nasto, xoogga saafiga ah uu ku dhaqmo shayga uu yahay eber.

∑ F = 0

F – w _x = 0

F = w _x

F = 14.7 Newton

(b) Baaxadda xoogga F haddii shay uu hoos ugu socdo si joogto ah 2 m/s ²

∑ F = ma

w _x – F = ma

14.7 – F = (3)(2)

14.7 – F = 6

F = 14.7–6

F = 8.7 Newton

(c) Baaxadda xoogga F haddii shay uu kor ugu socdo si joogto ah 2 m/s ²

∑ F = ma

F – w _x = ma

F – 14.7 = (3)(2)

F – 14.7 = 6

F = 14.7 + 6

F = 20.7 Newton
