Problems Show all work, formulae and reasoning to get any form of credit. Note that even if your final answer is correct, you may lose points if you leave out vital information. i. 1. The drawing shows a skateboarder moving at 5.4 m/s along a horizontal section of a track that is slanted upward by 48° above the horizontal at its end, which is 0.40 m above the ground. When she leaves the track, she follows the characteristic path of projectile motion. Ignoring friction and air resistance, 5.4 m/s 0.40 m a. Find the maximum height H to which she rises above the end of the track. b. How far from the edge does the skateboarder land on the ground?
