A small object at rest is let to slide straight down a 35° incline. After 0.45 m its speed is measured to be 1.6 m/s. Use the work-energy theorem to calculate the coefficient
of kinetic friction between the object and the incline plane. Hint: Draw the free-body
diagram of the object.
A) 0.54
B) 0.35
C) 0.39
D) 0.89
E) 0.56
