Olympiad 1

Two trucks roll down a slope, how much further apart will they be at the bottom?

Two trucks roll along a railway line separated by distance d_o with constant velocity v_o. The trucks roll down a slope of height h then reach another horizontal section where they move at velocity v separated by distance d.

Show that

$d = d_{o} \sqrt{1 + \frac{2 g h}{{v_{o}}^{2}}}$
