A bullet is fired with a muzzle velocity of 1446 ft/sec from a gun aimed at an angle of 5 degrees above the horizontal. Find the vertical component of the velocity.

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
