Characteristic path of projectile motion

Reference no: EM13544318

The drawing shows a skateboarder moving at 7.87 m/s along a horizontal section of a track that is slanted upward by 49.2 ° above the horizontal at its end, which is 0.739 m above the ground. When she leaves the track, she follows the characteristic path of projectile motion. Ignoring friction and air resistance, find the maximum height H to which she rises above the end of the track.
