47. An object undergoing projectile motion travels 1.00 x 102 m in the horizontal direction before returning to its initial height. If the object is thrown initially at a 30.0° angle from the horizontal, determine the x component and the y component of the initial velocity. (Neglect any effects due to air resistance.) Example 3-7
