A ski-jumper slides down a sloping ramp. At the bottom part of the ramp is an upward curve to the takeoff point at the end of the ramp. The start point is a vertical height of 25 m above the takeoff point. If the ski-jumper starts from rest at the start-point, calculate her speed at the takeoff point. Also, if the angle of takeoff velocity is 28 degrees above the horizontal, calculate the maximum height the jumper reaches above the takeoff point. A ski-jumper slides down a sloping ramp.
