Response:


To find the horizontal component ( X component), we can use trig by noting that from the diagram above we have formed a right triangle.  To find the x component:  use the formula:

X = V*cosθ
    = 17.6 *cos67.2
    = 6.82

To find the vertical component (Y component) we can use the formula:

Y = V*sinθ
    = 17.6 *sin67.2
    = 16.22
