Question
snowboarder slides down a 37° slope at a constant 4 m/s. What is the coefficient of kineticfriction?
Solution
To find the coefficient of kinetic friction, we can use the equation:
μk = tan(θ)
where μk is the coefficient of kinetic friction and θ is the angle of the slope.
Given that the snowboarder slides down a 37° slope, we can substitute this value into the equation:
μk = tan(37°)
Using a scientific calculator, we can find the tangent of 37°:
μk ≈ 0.7536
Therefore, the coefficient of kinetic friction is approximately 0.7536.
