Xazulula ijubane lokuqala libe izingxenye ezivundlile neziqondile zokunyakaza okubonakalayo

Izinkinga ezixazululiwe ekunyakazeni okuqoshwe nge-projectile - lungisa ijubane lokuqala libe izingxenye ezivundlile neziqondile

1. Ibhola elikhahlelwe lishiya phansi nge-engeli θ = 60^o ngejubane elingu-10 m/s. Bala izingxenye zejubane lokuqala!
Kwaziwa:
I-engeli (θ) = 60^o
Ijubane lokuqala (v)_o) = 10 m/s
Kufunwa: v_ox kanye no-v_oy
Isixazululo:
Xazulula ijubane lokuqala libe yi-x component (evundlile) kanye ne-y component (evundlile).
isono θ = v_oy /v_o —–> v_oy =v_o isono θ
cos θ = v_ox /v_o —–> v_ox =v_o cosθ

ingxenye engu-x (evundlile):
v_ox =v_o cos θ = (10 m/s)(cos 60^o) = (10 m/s)(0.5) = 5 m/s

ingxenye ka-y (eqondile):
v_oy =v_o isono θ = (10 m/s)(isono 60^o) = (10 m/s)(0.5√3) = 5√3 m/s

2. Into ishiya umhlabathi nge-engeli θ = 30^o ngengxenye engu-y yejubane engu-10 m/s. Bala ijubane lokuqala!
Kwaziwa:
I-engeli (θ) = 30^o
ingxenye ka-y (v_oy) = 10 m/s
Kufunwa: Ijubane lokuqala (v)_o)
Isixazululo:
v_oy =v_o isono θ
10 = (v_o)(isono 30^o)
10 = (v_o)(0.5)
v_o = 10/0.5
v_o = 20m/s

3. Ingxenye evundlile yejubane lokuqala ingu-30 m/s kanti ingxenye evundlile yejubane lokuqala ingu-40 m/s. Bala ijubane lokuqala.
Kwaziwa:
Ingxenye evundlile yejubane lokuqala (v)_ox) = 30 m/s
Ingxenye eqondile yejubane lokuqala (v)_oy) = 40 m/s
Kufunwa: Ijubane lokuqala (v)_o)
Isixazululo:
v_o² =v_ox² +v_oy² = 30² 40 +² = 900 + 1600 = 2500
v_o = √2500
v_o = 50m/s

4. Ibhola elincane liphakanyiswa ngokuvundlile ngejubane lokuqala v_o = 6m/s. Bala ingxenye ka-x kanye nengxenye ka-y yejubane lokuqala.
Kwaziwa:
Ijubane lokuqala (v)_o) = 6 m/s
Kufunwa: i-vox kanye ne-v_oy
Isixazululo:
Ibhola lihamba ngokuvundlile ukuze ingxenye yejubane evundlile (v)_ox) = ijubane lokuqala (v_o) = 6 m/s. Ingxenye eqondile yejubane (v)_oy= 0.
