Askier is moving down a snowy hill with an acceleration of 0.40 m/s2. the angle of the slope is 5.0∘ to the horizontal. what is the acceleration of the same skier when she is moving down a hill with a slope of 10 ∘? assume the coefficient of kinetic friction is the same in both cases.

1.25377 m/s²

Explanation:

m = Mass of person

g = Acceleration due to gravity = 9.81 m/s²

= Coefficient of friction

= Slope

From Newton's second law

Applying to the above equation and

The acceleration of the same skier when she is moving down a hill is 1.25377 m/s²
