1) [8 pts] As shown in the diagram, a skier starts from rest down a slope that has an angle of e=310 from the horizontal. The coefficient of kinetic friction between her skis and the snow is uk=0.13. After a distance of 72.0 m along the slope she goes over a cliff without slowing down. She lands a vertical distance h=8.2 m below the cliff edge. a) Find her acceleration down the slope. b) Find her speed at the cliff edge. c) Find her speed as she lands on the slope below the cliff.
