A novice skier starting from rest, slides down an icy frictionless 8.0° incline whose vertical height is 105 m How fast is she going when she reaches the bottom?
Velocity of novice skier when she reaches bottom
Answer to Problem 31P
Solution:Velocity of novice skier when she reaches bottom is 45.36 m/s.
Explanation of Solution
Given:
Formula Used:
The forces acting on the skier is the force due to gravity and normal force. Work done by the normal force is zero because normal force is perpendicular to the direction of motion.
According to law of conservation of energy
Where m is the mass of skier,
Calculations: Substituting all the known values in above equation and solve for final velocity:
Velocity of novice skier when she reaches bottom is
Conclusion:Novice skier reaches the bottom at
