A man is riding on a cycle with velocity \( 7.2 \mathrm{~km} / \mathrm{hr} \) up a hill having a slope 1 in 20 . The total mass of the man and cycle is \( 100 \mathrm{~kg} \). The power of the man is
\( \mathrm{P} \)
(1) \( 200 \mathrm{~W} \)
(2) \( 175 \mathrm{~W} \)
W
(3) \( 125 \mathrm{~W} \)
(4) \( 98 \mathrm{~W} \)
