A skier leaves the starting gate at the top of a ski jump with an initial speed of 4 m/s. the starting position is 120 m higher than the end of the ramp, which is 3 m above the snow. FIND THE FINAL SPEED of the skier if he lands 145 m down the 20 degrees slope. assume there is no friction on the ramp, but air resistance causes a 50% loss in the final kinetic energy. The GPS reading of the elevation of the skier is 4212 m at the top of the jump and 2017 m at the landing point.
