A93.5 kg snowboarder starts from rest and goes down a 60 degree slope with a 45.7 m height to a rough horizontal surface that is 10.0 m long and a coefficient of kinetic friction of 0.102. the then snowboarder goes up a slope with angle of 30 degrees up coming to a stop and then sits to stay in the same place. be considered frictionless. a. what is the speed of the snowboarder at the bottom of the 60 degree slope? b. what is the speed of the snowboarder at the bottom of the 30 degree slope? c. what is the final height of the snowboarder above the horizontal surface? until both slopes are smooth and can
