Goli is a popular game in Indian villages, played with small glass balls known as golis. One player's goli is located at a distance of 2.0 m from the second player's goli. The second player must project his goli by keeping the thumb of the left hand at the position of his goli, holding the goli between his two middle fingers, and executing the throw. The second player wins if the projected goli strikes the first play

Correct answer: D. 10

The vertical motion of the goli is given by h = 1 2 g t^2 . Substituting the given values, 0.196 = 1 2 9.8 t^2 . t^2 = 0.196 4.9 = 0.04 t = 0.2 s . The horizontal motion is uniform, so the range is R = u t . Substituting R = 2.0 m and t = 0.2 s , we get 2.0 = u 0.2 . u = 2.0 0.2 = 10 m/s .
