A mass M slides upward along a rough plane surface inclined at an angle Theta: θ = 0.19 radians to the horizontal. Initially, the mass has a speed V₀ = 3.49 m/s before it slides a distance L = 1.0 m up the incline. After sliding this distance, the new speed of the mass is V₀/5 measured in m/s. What is the coefficient of kinetic friction μk between the mass and the incline?
