A golfer on a level fairway hits a ball at an angle of 28° to the horizontal that travels 109 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 109 yd. At what angle was the second ball hit? (Neglect air resistance.)

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
