A stone is thrown at an angle of 30° above the horizontal from the top edge of a cliff with an initial speed of 19.6 m/s. A stop watch measures the stone's trajectory time from top of cliff to bottom to be 6.7 s. How far out from the cliff's edge does the stone travel horizontally? (g = 9.8 m/s2 and air resistance is negligible)

A) 58 m

B) 114 m

D) 175 m
