Konzani liwiro loyambirira kukhala magawo opingasa ndi olunjika a kayendedwe ka projectile

Mavuto othetsedwa pakuyenda kwa projectile - sinthani liwiro loyambirira kukhala magawo opingasa ndi olunjika

1. Mpira wokankha umachoka pansi pa ngodya θ = 60^o ndi liwiro la 10 m/s. Werengani zigawo zoyambira za liwiro!
Zodziwika:
Ngodya (θ) = 60^o
Liwiro loyambirira (v)_o) = 10 m/s
Akufuna: v_ox ndi v_oy
Yankho:
Konzani liwiro loyambirira kukhala gawo la x (lopingasa) ndi gawo la y (lopingasa).
tchimo θ = v_oy /v_o —–> v_oy =v_o tchimo θ
cos θ = v_ox /v_o —–> v_ox =v_o cos θ

gawo la x (lopingasa):
v_ox =v_o cos θ = (10 m/s)(cos 60^o) = (10 m/s)(0.5) = 5 m/s

gawo la y (loyima):
v_oy =v_o uchimo θ = (10 m/s)(uchimo 60^o) = (10 m/s)(0.5√3) = 5√3 m/s

2. Chinthu chimachoka pansi pa ngodya θ = 30^o ndi gawo la y la liwiro la 10 m/s. Werengani liwiro loyambirira!
Zodziwika:
Ngodya (θ) = 30^o
gawo la y (v)_oy) = 10 m/s
Akufuna: Liwiro loyambirira (v)_o)
Yankho:
v_oy =v_o tchimo θ
10 = (v_o)chimo 30^o)
10 = (v_o) (0.5)
v_o = 10/0.5
v_o = 20 m/s

3. Chigawo chopingasa cha liwiro loyambira ndi 30 m/s ndipo chigawo chopingasa cha liwiro loyambira ndi 40 m/s. Werengani liwiro loyambira.
Zodziwika:
Gawo lolunjika la liwiro loyambirira (v)_ox) = 30 m/s
Gawo loyima la liwiro loyambirira (v)_oy) = 40 m/s
Akufuna: Liwiro loyambirira (v)_o)
Yankho:
v_o² =v_ox² +v_oy² = 30² + 40² 900 + 1600 = 2500
v_o = √2500
v_o = 50 m/s

4. Mpira wawung'ono umayendetsedwa mopingasa ndi liwiro loyambirira v_o = 6m/s. Werengani gawo la x ndi gawo la y la liwiro loyambirira.
Zodziwika:
Liwiro loyambirira (v)_o) = 6 m/s
Akufuna: vox ndi v_oy
Yankho:
Mpira umayenda mopingasa kotero kuti gawo lopingasa la liwiro (v)_ox) = liwiro loyambirira (v_o) = 6 m/s. Chigawo choyima cha liwiro (v)_oy) = 0.
