the drawing shows a skateboarder moving at 6.00m/s along a horizontal section of a track that is slanted upwards by theta=47.o degrees above the horizontal at its end,which is 0.750 m above the ground .when she leaves the track ,she follows the charecteristic path of projectile motion .ignoring friction and air resistance ,find the maximum height Hto which she rises aove the end of the track
