Dhaqdhaqaaq xawaare joogto ah leh - dhibaatooyinka iyo xalalka

Dhibaatooyinka lagu xalliyay Dhaqdhaqaaqa Toosan - Xawaaraha joogtada ah

1. Gaadhigu wuxuu ku socdaa xawaare joogto ah 10 m/s. Go'aami masaafada 10 ilbiriqsi iyo 60 ilbiriqsi kadib.

Solution

Xawaaraha joogtada ah ee 10 mitir/ilbiriqsi macnaheedu waa in gaarigu uu socdo 10 mitir 1 ilbiriqsi kasta.

2 ilbiriqsi ka dib, gaarigu wuxuu socdaa 20 mitir,

5 ilbiriqsi ka dib, gaarigu wuxuu socdaa 50 mitir,

10 ilbiriqsi ka dib, gaarigu wuxuu socdaa 100 mitir,

60 ilbiriqsi ka dib, gaarigu wuxuu socdaa 600 mitir.

2. Gaarigu wuxuu ku socdaa waddo toosan xawaare joogto ah oo ah 72 km/saacaddii. Go'aami masaafada gaariga ka dib 2 daqiiqo iyo 5 daqiiqo.

Solution

72 km/saacaddii = (72)(1000 mitir) / 3600 ilbiriqsi = 72,000 / 3600 ilbiriqsi = 20 mitir/ilbiriqsi.

Xawaaraha joogtada ah ee 20 mitir/ilbiriqsi wuxuu la macno yahay in gaarigu uu socdo 20 mitir 1 ilbiriqsi kasta.

120 ilbiriqsi ama 2 daqiiqo ka dib, gaarigu wuxuu socdaa 20 mitir x 120 = 2400 mitir,

300 ilbiriqsi ama 5 daqiiqo ka dib, gaarigu wuxuu socdaa 20 mitir x 300 = 6000 mitir.

3. Jidhku wuxuu ku socdaa waddo toosan 100 mitir 50 ilbiriqsi gudahood. Go'aami xawaaraha jirka.

Solution

100 mitir / 50 ilbiriqsi = 10 mitir / 5 ilbiriqsi = 2 mitir/ilbiriqsi.

4. Go'aami xawaaraha sida ku cad jaantuska hoose….

Solution

Xawaaraha = Masaafada / waqtiga dhaafay

Xawaaraha = 2 mitir / 1 ilbiriqsi = 4 mitir / 2 ilbiriqsi = 6 mitir / 3 ilbiriqsi = 8 mitir / 4 ilbiriqsi = 2 mitir/ilbiriqsi.

5. Baabuurta A iyo B waxay isku soo dhawaadaan waddooyin is barbar socda. Marka masaafada u dhaxaysa labada baabuur ay tahay 100 mitir, baabuurka A wuxuu ku socdaa xawaare joogto ah oo ah 10 m/s, baabuurka B wuxuu ku socdaa xawaare joogto ah oo ah 40 m/s. Go'aami (a) masaafada baabuurka A ka hor inta uusan dhaafin baabuurka B (b) muddada u dhaxaysa kahor inta uusan gaadhiga B dhaafin baabuurka A.

Solution

Gaariga A wuxuu ku socdaa xawaare joogto ah 10 mitir/ilbiriqsi, taasoo la micno ah in gaariga A uu u socdo ilaa 10 mitir 1 ilbiriqsi kasta. 2 ilbiriqsi ka dib, gaarigu wuxuu u socdaa ilaa 20 mitir.

Gaariga B wuxuu ku socdaa xawaare joogto ah 40 mitir/ilbiriqsi, taasoo la micno ah in gaariga B uu u socdo ilaa 40 mitir 1 ilbiriqsi kasta. 2 ilbiriqsi ka dib, gaariga B wuxuu u socdaa ilaa 80 mitir.

20 mitir + 80 mitir = 100 mitir.

(a) Masaafada gaariga A ka hor inta uusan dhaafin gaariga B waa 20 mitir. Masaafada gaariga B ka hor inta uusan dhaafin gaariga A waa 80 mitir.

(b) Muddada u dhaxaysa baabuurka B ka hor inta uusan dhaafin baabuurka A waa 2 ilbiriqsi. Muddada u dhaxaysa baabuurka A ka hor inta uusan dhaafin baabuurka B waa 2 ilbiriqsi

5. Haddii mitirka xawaaraha baabuur waxay muujinaysaa 108 km/saacaddii, go'aami masaafada uu gaarigu ku safray hal daqiiqo gudaheed.

Xalka:

Qalabka xawaaraha lagu cabbiro waa qalab lagu cabbiro xawaaraha. Xawaaraha gaarigu waa 108 km/saacaddii.
108 km / saac = (108) (1000 mitir) / 3600 ilbiriqsi = 30 mitir/ilbiriqsi.

1 daqiiqo = 60 ilbiriqsi

Xawaaraha gaariga 30 mitir/ilbiriqsi waxay la macno tahay in gaarigu uu u socdo ilaa 30 mitir hal ilbiriqsi gudaheed.

Ka dib 1 ilbiriqsi, gaarigu wuxuu u socdaa ilaa 1 x 30 mitir = 30 mitir.

Laba ilbiriqsi ka dib, gaarigu wuxuu u socdaa ilaa 2 x 30 mitir = 60 mitir.

Laba ilbiriqsi ka dib, gaarigu wuxuu u socdaa ilaa 60 x 30 mitir = 1800 mitir.

6. Tom tuuro a kubad toos ah Andrew. Tom iyo Andrew way wada joogaan u kala fog ilaa 10.08 metersKubadda waa la tuuray safka hore iyo dhaqdhaqaaqyo at 20 m/s (iska indha tir cufisjiidadka). Andrew dhacays kubadda 4.00 x 10^-3 ilbiriqsiyo ka dib markii kubadda la tuuray. garaace Dhaqaajiya si joogto ah xawaaraha xawaaraha 5.00 m/s, kubadda waxaa ku dhufta garaace ka dib markii ay Weerarku wuxuu u dhaqaaqaa ilaa…

La yaqaan:

Masaafada u dhaxaysa Tom iyo Andrew = 10.08 mitir

Xawaaraha kubadda (v) = 20 m/s

Muddada (t) = 4 x 10^-3 Ilbiriqsiyo = 0.004 ilbiriqood

Xawaaraha garaacaha (v) = 5 m / s

SE buska: Kubbada waxaa ku dhufta qofka wax ku dhufta ka dib markii kubbadu ay u dhaqaaqday ilaa…

Xalka:

Masaafada Kubadda:

s₁ = vt = (20)(0.004) = 0.08 mitir

Masaafada uu ku socdo weeraryahanka:

s₂ = vt = 5 t

Masaafada Kubadda + masaafada qofka wax ku dhuftay = masaafada u dhaxaysa Tom iyo Andrew.

0.08 + 5 t = 10.08

5 t = 10.08 – 0.08

5 t = 10

t = 10 / 5

t = 2 ilbiriqsi

Masaafada uu ku socdo weeraryahanka:

s₂ = vt = 5 t = (5) (2) = 10 mitir

7. Ugaarsade gaarigiisa wata ayaa eryanaya deero. Gaarigu wuxuu ku socdaa 72 km/saacaddii deeradana waxay ku socotaa xawaare dhan 64.8 km/saacaddii. Marka masaafada u dhaxaysa gaariga iyo deerada ay tahay 2012 mitir, ugaadhsade wuxuu rasaas ku riday qorigiisa. Rasaasta qoriga waxay ka soo baxaysaa 200 m/s. Go'aami muddada deerada la tooganayo.

A. 0.5 ilbiriqsi

B. 1 ilbiriqsi

C. 1.25 ilbiriqsi

D. 1.5 ilbiriqsi

La yaqaan:

Xawaaraha gaariga (v_b= 72 km/h = (72) (1000 m) / 3600 s = 20 m/s

Xawaaraha deerada (v_r= 64.8 km/h = (64.8) (1000 m) / 3600 s = 64800 m / 3600 s = 18 m/s

Marka rasaasta la rido, masaafada u dhaxaysa gaariga iyo deerada (s) = 202 mitir

Xawaaraha dabka (v_p) = 20 m/s + 200 m/s = 220 m/s

Hubka ay haystaan ​​ugaarsatada ku jira gaari ku socda xawaare dhan 20 m/s si xawaaraha gaariga loogu daro xawaaraha rasaasta.

SE buska: Go'aami muddada deerada la tallaalayo

Xalka:

Ka fikir baabuurta iyo deerada oo si joogto ah u socda.

Isle'egta: v = s / t ama s = vt

v = xawaare, s = masaafada, t = kala-goynta waqtiga

Masaafada = 202 + X_r = 202 + v_r t = 202 + 18 t

Masaafada = Y_p =v_p t = 220 t

Masaafada uu maro deerada = masaafada uu maro xabadu

202 + 18 t = 220 t

202 = 220 t – 18 t

202 = 202 t

t = 202 / 202

t = 1 ilbiriqsi

Jawaabta saxda ah waa B.
