Ответ:
126.03 ft/sec
Explanation:
From the question above,
V₁ = VsinФ Equation 1
Where V₁ = vertical component of the velocity, V = Velocity acting on the x-y plane, Ф = angle to the horizontal.
Given: V = 1446 ft/sec, Ф = 5°
Substitute into equation 1
V₁ = 1446sin(5)
V₁ = 1446(0.0872)
V₁ = 126.03 ft/sec.
Hence the vertical component of the velocity = 126.03 ft/sec
