A placekicker is about to kick a field goal. The ball is 27.0 m from the goal post. The ball is kicked with an initial velocity of 19.4 m/s at an angle above the ground. Between what two angles, 1 and 2, will the ball clear the 3.0-m-high crossbar? (Hint: The following trigonometric identities may be useful sec = 1/(cos ) and sec2 = 1 + tan2 .)
