Your cousin jannik skis down a blue square ski slope, with an initial speed of 3.6 m/s. he travels 15 m down the mountain side before coming to a flat landing. jannik estimates the blue skislope has a 40 percent grade, or 18ā¦ incline above the horizontal and that he and his skis have a total mass of 58.0 kg. suppose that the hillside is not frictionless, so that jannikās speed at the bottom of the slope is 7.8 m/s. what is the energy lost due to friction when jannik reaches the flat landing? justify your response.
