David puts a stone in his 0.52 m. long slingshot and spins it around his head with a frequency of 3.7 Hz. He releases the stone 1.2 m. above the ground and at an angle of 38 degrees above the horizontal, and the stone strikes Goliath in the shoulder, 2.4 m. above the ground. How far was Goliath from David? (There are 2 possible answers.)

Only serious answer please? Thanks again!
