A skilled skier knows to jump upward before reaching a downward slope. Consider a jump in which the launch speed V0= 12.5 m/s, the launch angle 8.2 degrees, the initial course is approximately flat, and the steeper track has a slope of 11.8 degrees.

(a) In the landing, what is the angle ? between the skier's path and the slope?

(b) how far below the launch level does the skier land and
