A ball is thrown vertically upward. It has a speed of \( 10 \mathrm{~m} / \mathrm{sec} \) when it has reached one half of its
\( \mathrm{P} \) maximum height. How high does the ball rise?

W (Take \( g=10 \mathrm{~m} / \mathrm{s}^{2} \) )
(a) \( 10 \mathrm{~m} \)
(b) \( 5 \mathrm{~m} \)
(c) \( 15 \mathrm{~m} \)
(d) \( 20 \mathrm{~m} \) (2005)
