6. A 59.0kg snowboarder descends a 1.30km ski y hill from the top of a mountain to the base (see diagram). The slope is at an angle of 14.0° to the horizontal. Determine the snowboarder's 1.3 km gravitational potential energy relative to the 0 = 14° mountain base when she is at the top. Determine Drawing not to scale the energy loss due to friction if the snowboarder has a final speed o the mountain base. What will be the average coefficient of kinetic fri- Answer: The total gravitational potential energy was 182kJ, or 1.82 amount of energy loss was 177kJ, or 1.77×10°J. As inetic friction will be approximatel coefficient of k

Question
6. A 59.0kg snowboarder descends a 1.30km ski y hill from the top of a mountain to the base (see diagram). The slope is at an angle of 14.0° to the horizontal. Determine the snowboarder's 1.3 km gravitational potential energy relative to the 0 = 14° mountain base when she is at the top. Determine Drawing not to scale the energy loss due to friction if the snowboarder has a final speed of 13.5m/s at the mountain base. What will be the average coefficient of kinetic friction? Answer: The total gravitational potential energy was 182kJ, or 1.82×10°J.The amount of energy loss was 177kJ, or 1.77×10'J. As a result, the average coefficient of kinetic friction will be approximately 1.00. Source: modified from Nelson, Physics 12, 2009, p. 181, Question #7
