In the figure, a block slides along a track from one level
\( \mathrm{P} \)
to a higher level, by moving through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance \( d \). The block's initial speed \( v_{0} \) is \( 6 \mathrm{~m} / \mathrm{s} \), the height difference \( h \) is \( 1.1 \mathrm{~m} \) and the coefficient of kinetic friction \( \mu \) is 0.6 . The value of \( d \) is
(1) \( 1.17 \mathrm{~m} \)
(2) \( 1.71 \mathrm{~m} \)
(3) \( 7.11 \mathrm{~m} \)
(4) \( 11.7 \mathrm{~m} \)
