In the javelin throw at a track-and-field event, the javelin is launched at a speed of 29 m/s at an angle of 368 above the horizontal. As the javelin travels upward, its velocity points above the horizontal at an angle that decreases as time passes. How much time is required for the angle to be reduced from 368 at launch to 188?
