Muddada u dhaxaysa (t) = 60 – 30 = 30 daqiiqo = 0,5 saacadood
La weydiiyay: Masaafada la safray
Jawaab:
Laga bilaabo daqiiqaddii 30aad ilaa daqiiqaddii 60aad, gaariga ayaa la ciyaaray.dhaqdhaqaaq toosan oo siman.

Bedka diyaaradda 1 = bedka CD-ga saddexagalka ah = ½ (6-5)(40-20) = ½ (1)(20) = 10
Bedka diyaaradda 2 = bedka saddexagalka DE = ½ (8-6)(20-0) = ½ (2)(20) = 20
Bedka diyaaradda 3 = bedka labajibbaaran = (6-5)(20-0) = (1)(20) = 20

Masaafada u dhaxaysa waqtiga u dhexeeya t = 5 ilbiriqsi ilaa t = 8 ilbiriqsi:

Dardargelintu waa tiro isle'eg, halka xawaaruhu yahay tiro vector ah. Dardargelintu had iyo jeer waa togan, halka dardargelintu ay noqon karto mid togan ama taban. Dardargelintu waa togan haddii xawaaruhu kordho (jihada xawaaruhu = jihada dardargelinta), dardargelintuna waa taban haddii xawaaruhu hoos u dhaco (jihada xawaaruhu waa ka soo horjeedka jihada dardargelinta).
Mid ka mid ah qaababka GLBB:
v_t =v_o + at —-> v_t - v_o = at —-> a = v_t - v_o /t
Isticmaal qaacidadan si aad u xisaabiso dardargelinta. Maadaama aan xisaabinayno dardargelinta, ee aan xisaabinayno dardargelinta, iska dhaaf calaamadda taban.
Xawaaraha AB = (25 – 20) / (20 – 0) = 5/20 = 1/4 = 0,25 m/s²
Xawaaraha BC = (45 – 25) / (40 – 20) = 20/20 = 1 m/s²
Xawaaraha CD = (35 – 45) / (50 – 40) = 10 / 10 = 1 m/s²
Xawaaraha DE = (25 – 35) / (70 – 50) = 10 / 20 = 1/2 = 0,5 m/s²
Xawaaraha EF = (0 – 25) / (90 – 70) = 25/20 = 5/4 = 1,25 m/s²
Jawaabta saxda ah waa C.

9. Xawaaraha (v) ee shay ku socda xariiq toosan wuxuu la mid yahay waqtiga (t) sida ku cad garaafka v-t. Masaafada uu walaxdu ku safray 10 ilbiriqsi gudahood waa…

Dood
Waa la yaqaan (xog ku salaysan garaafka):
Xawaaraha bilowga ah (v)_o= 0
Xawaaraha kama dambaysta ah (v)_t) = 20 m/s
Muddada (t) = 4 ilbiriqsi
La weydiiyay:
Masaafada lagu safray 10 ilbiriqsi gudahood?
Jawaab:
Saddex qaacido oo loogu talagalay dhaqdhaqaaqa toosan ee si siman u degdegsan (GLBB):
v_t =v_o + at
s = v_o t + ½ at²
v_t² =v_o² + 2 dhidib
Sharaxaadda qaacidada: v_t = xawaaraha kama dambaysta ah, v_o = xawaaraha bilowga ah, a = dardargelinta, t = waqtiga u dhexeeya, s = masaafada la safray
Xisaabi dardargelinta (a):
v_t =v_o + at
20 = 0 + a (4)
20 = 4 a
a = 20/4
a = 5 m/s²
Xisaabi masaafada la safray 10 ilbiriqsi gudahood:
s = v_o t + ½ at²
s = (0)(10) + ½ (5)(10)²
s = ½ (5)(100)
s = (5)(50)
s = 250 mitir
Jawaabta saxda ah waa D.

10. Haddii shay kor looga soo tuuro dusha sare ee dhulka, markaa garaafka cabbirka dardargelinta uu walaxdu la kulmay waa...
Dood
Marka shay kor looga soo tuuro dusha sare ee Dhulka, dardargelinta uu walaxdu la kulmo waa dardargelinta cufisjiidadka Dhulka. Dardargelinta cufisjiidadka Dhulka waa qiime joogto ah oo ah 9,8 m/s2.² jihada dardargelinta cufisjiidadka dhulku had iyo jeer waxay ku socotaa bartamaha Dhulka.
Dardargelinta joogtada ah waxaa lagu gartaa xariiq toosan oo barbar socota dhidibka t iyo mid toosan oo u janjeerta dhidibka a.
Jawaabta saxda ah waa D.

11. Shay ayaa ku socda xawaare sida ku cad jaantuska hoose. Masaafada uu shaygu ku safray 20 ilbiriqsi gudahood waa….

1. 600 m
2. 500 m
3. 200 m
4. 100 m

Dood
Masaafada la safray 0 - 10 ilbiriqsi = bedka labajibbaaran + bedka saddexagalka
Bedka labajibbaaran = (20-0)(10-0) = (20)(10) = 200 mitir
Bedka saddexagalka = (1/2)(10-0)(40-20) = (1/2)(10)(20) = (5)(20) = 100 mitir
Masaafada la safray 0 – 10 ilbiriqsi = 200 mitir + 100 mitir = 300 mitir
 
Masaafada lagu safray 10 - 20 ilbiriqsi = bedka saddexagalka
Bedka saddexagalka = (1/2)(20-10)(40-0) = (1/2)(10)(40) = (5)(40) = 200 mitir

Masaafada uu walax ku safray 0 - 20 ilbiriqsi gudahood:
300 mitir + 200 mitir = 500 mitir

Jawaabta saxda ah waa B.
