    1058.78 ft/sec

    Explanation:

    Horizontal Component of Velocity; This is the velocity of a body that act on the horizontal axis. I. e Velocity along x-axis

    The horizontal velocity of a body can be calculated as shown below./

    Vh = Vcos∅ ... Equation 1

    Where Vh = horizontal component of the velocity, V = The velocity acting between the horizontal and the vertical axis, ∅ = Angle the velocity make with the horizontal.

    Given: V = 1178 ft/sec, ∅ = 26°

    Substitute into equation 1

    Vh = 1178cos26

    Vh = 1178 (0.8988)

    Vh = 1058.78 ft/sec

    Hence the horizontal component of the velocity = 1058.78 ft/sec
