svet-max [94.6K]

Answer:

V_y = 16.44\ m/s

V_y = 7.32\ m/s<em />

Explanation:

Given

\theta = 24

Velocity\ (V) = 18m/s

Required

Determine the vertical and horizontal components

The vertical (Vy) and horizontal (Vx) components is calculated as thus:

V_x = Vcos\theta

V_y = Vsin\theta

Calculating Vertical Components:

V_y = Vsin\theta

V_y = 18 * sin24

V_y = 18 * 0.40673664307

V_y = 7.32125957526

V_y = 7.32\ m/s<em> --- Approximated</em>

Calculating Horizontal Components:

V_x = Vcos\theta

V_x = 18 * cos24

V_x = 18 * 0.91354545764

V_x = 16.4438182375

V_x = 16.44\ m/s <em>--- Approximated</em>
