Answer:

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
