Solution of the D1 12. The skier of mass m = 70 kg falls without an initial speed of the slope, forming an angle a = 30 ° to the horizontal, not pushing sticks. L = length of the descent of 100 m, the coefficient of friction of the ski snow f = 0,1. The strength of the air resistance is proportional to the square of the speed R = 0,4v2. Determine the speed of the skier at the end of the descent.
