A \( 10.0 \mathrm{~kg} \) crate slides along a horizontal frictionless surface at a constant speed of \( 4.0 \mathrm{~m} / \mathrm{s} \). The crate then slides down a frictionless incline and across a second horizontal surface as shown in the figure.

While the crate slides along the upper surface, how much gravitational potential energy does it have compared to what it would have on the lower surface?
(A) \( 140 \mathrm{~J} \)
(B) \( 490 \mathrm{~J} \)
(C) \( 80 \mathrm{~J} \)
(D) \( 290 \mathrm{~J} \)
