A skateboarder moves at 5.4m/s along a horizontal track... MAX height? (more info. in description)?

A skateboarder moves at 5.4m/s along a horizontal track that is slanted up by 48degrees above the horizontal at its end, which is .40m above the ground. When she leaves the track she follows a characteristic path of projectile motion. Ignoring friction and air resistance, find the maximum height ti which she rises above the end of the track.
