Shouldn't he reach the top?

A skier is about to attempt a daring jump. He starts from the top of a frictionless slope that turns upward into a circular arc, as shown in the figure.

What is the velocity of the skier $$($$in $$\text{m/s})$$ at the highest point of his trajectory (after breaking off the slope)?

Details and Assumptions:

• Use $$g=-10 \text{ m/s}^2.$$
• The skier's friends, knowing the monumental stupidity of the skier's stunt, have prepared a net to catch the skier as he falls.
