A \( 2 \mathrm{~kg} \) mass starts from rest on an inclined smooth surface with inclination \( 30^{\circ} \) and length \( 2 \mathrm{~m} \). How much will it travel before coming to rest on a frictional surface with frictional coefficient of \( 0.25 \)
[UPSEAT 2003]
(a) \( 4 m \)
(b) \( 6 m \)
(c) \( 8 \mathrm{~m} \)
(d) \( 2 \mathrm{~m} \)
