60.0 kg skier is moving down a snowy hill inclined at 5 degrees above the horizontal with an acceleration of 0.4m/s2 a. What is the acceleration of the same skier when she is moving down a hill with a slope of 10 degrees? Assume that the coefficient of friction is the same for both cases. b. How much time will it take her to move 25.0m along 10 degree slope? c. After 25.0m, the slope levels out and becomes flat and smooth. She skis into a snowbank which slows her to a stop in a distance of 0.80m. How much force does the snowbank exert on her? d. How much force does she exert on the snowbank

Question
A 60.0 kg skier is moving down a snowy hill inclined at 5 degrees above the horizontal with
an acceleration of 0.4m/s2
a. What is the acceleration of the same skier when she is moving down a hill with a
slope of 10 degrees? Assume that the coefficient of friction is the same for both
cases.
b. How much time will it take her to move 25.0m along 10 degree slope?
c. After 25.0m, the slope levels out and becomes flat and smooth. She skis into a
snowbank which slows her to a stop in a distance of 0.80m. How much force
does the snowbank exert on her?
d. How much force does she exert on the snowbank?
