Question

1. This freestyle skier has jumped 10 feet into the air from the tip of the ski jump.
   
   a) Calculate the initial vertical component of the skiers velocity as they left the tip of the ski jump.
   b) If the ski jump is at an angle of 40^o from the vertical; calculate the magnitude of the initial velocity of the skier.
   c) If the skier travelled 5 m along the 40o slope before the jump, and the coefficient of kinetic friction between their ski and the snow was 0.05, calculate their speed at the bottom of the slope.
   d) The height of the tip of the jump from the ground is 2 m. Calculate the distance the skier travels if they land on horizontal ground.
   
   [Note: in reality they land on a down hill slope to reduce injuries.]
