What angle was the second ball hit?

Question

A golfer on a level fairway hits a ball at an angle of 23° to the horizontal that travels 105 yd before striking the ground. He then hits another ball from the same spot with the same speed, but at a different angle. This ball also travels 105 yd. At what angle was the second ball hit? (Neglect air resistance.)

Answer 1

The golfer hit the ball at the same speed and the ball traveled the same distance (105 yds). The first ball was hit at an angle of 23 degrees. The second ball was hit an an angle of 67 degrees (complimentary angle). 90-23 = 67 degrees.
