8. A ski jumper has the take-off conditions shown. Determine the total time tr (in seconds) during which the skier is in the air. Assume that the landing zone BC is straight. 30 m -115 km/h Landing Zone 60 m 37.5° BC= 45 m 9. For the previous problem, determine the horizontal distance xr (m) from the take-off point A to the location where the skier first touches down in the landing zone.
