Please Help! Physics Problem?

Scarlet has taken a summer job at a water park. In her act she glides up a 2.0 m high frictionless ramp then sails over a 5 m wide cage filled with hungry sharks. What is the minimum speed (in m/s) at which she can begin her ascent of the ramp in order to avoid landing in the cage with the sharks? (Hint: how fast must she be going at the top of the ramp?)
