One stone is projected horizontally from a \( 20 \mathrm{~m} \) high cliff with an initial speed of \( 10 \mathrm{~ms}^{-1} \). A second stone is simultaneously dropped from that cliff. Which of the following is true?
(A) Both strike the ground with the same speed.
\( \mathrm{P} \)
(B) The stone with initial speed \( 10 \mathrm{~ms}^{-1} \) reaches the ground first.
W
(C) Both the stones hit the ground at the same time.
(D) The stone which is dropped from the cliff reaches the ground first.
