Problem
You throw a ball at angle θ and measure its horizontal range, R. You now throw the same ball again at the same angle, but with twice the original speed. Its horizontal range, compared to your first throw (in both cases, the ball lands at the same height from which it was thrown) would be
(A) 1.4R
(B) 0.5R
(C) 2R
(D) 4R
(E) the same
