Waa la ogyahay in:
v_o = 36 km/h = 36000 m / 3600 s = 10 m/s
v_t = 72 km/h = 72000 m / 3600 s = 20 m/s
s = 150 mitir
Waxaa la weydiiyay: waqtiga safarka (t)?
Jawaab:
Waxaa jira saddex qaacido oo loogu talagalay dhaqdhaqaaqa toosan ee si siman u degdegsan (GLBB):
v_t =v_o + at
s = vot t + ½ at²
v_t² =v_o² + 2 dhidib
Iyada oo ku saleysan xogta la yaqaan, si toos ah uma xisaabin karno waqtiga safarka annagoo adeegsanayna mid ka mid ah qaacidooyinka kor ku xusan.
Marka hore xisaabi dardargelinta (a) adoo isticmaalaya qaacidada 3aad.
v_t² =v_o² + 2 dhidib
20² = 10² + 2 a (150)
400 = 100 + 300 a
400 – 100 = 300 a
300 = 300 a
a = 300/300
a = 1 m/s²
Xisaabi muddada u dhaxaysa (t) adoo isticmaalaya qaacidada 1aad.

0 = 20 + a 5
-20 = 5a
a = -20/5
a = -4 m/s²

Waa la ogyahay in:
v_o = 10m/s
v_t = 20m/s
t = 8 ilbiriqsi
La weydiiyay: Masaafada la safray (yada)?
Jawaab:

Jawaabta saxda ah waa E.

18. Garaafka dhinaca ku yaal waa garaaf shay ku socda xariiq toosan. Masaafada uu shaygu u socdo inta u dhaxaysa 0 iyo 6 ilbiriqsi waa...

A. 40 mitir
B. 45 mitir
Q. 50 mitir
D. 55 mitir
Q. 60 mitir
Dood
Masaafada la safray = bedka garaafka (s = vt)
Masaafada la safray 1 = ½ (10)(3) = (5)(3) = 15 mitir
Masaafada la safray 2 = (10)(6-3) = (10)(3) = 30 mitir
Wadarta masaafada la safray:
15 mitir + 30 mitir = 45 mitir
Jawaabta saxda ah waa B
