(7\%) Problem 12: A football is punted from the ground, it passes through the apex of its flight, and it begins its downward decent, as shown. When its height above the field is \( h=1.4 \mathrm{~m} \), the horizontal and vertical components of its velocity are observed to have the values horizonal \( =15 \mathrm{~m} / \mathrm{s} \) and \( v_{\text {verical }}=4.25 \mathrm{~m} / \mathrm{s} \), respectively. Use a Cartesian coordinate system with the origin located at the initial position of the football. Ignore air resistance. A. \( 50 \% \) Part (a) Determine the magnitude of the horizontal component of the football's initial velocity vo, , in terms of horizonal \[ v_{0, x}= \] Feedhacki ins deduction per frebouck.
