Answer:
The coefficient of kinetic friction between the cart and the track is 0.114
Step-by-step explanation:
Given;
Angle of inclination, θ = 10°
Acceleration of the cart, a = 0.60 m/s²
Apply Newton's law of motion
mgsinθ - μkmgcosθ = ma
Divide through by mass, m
gsinθ - μkgcosθ = a
μkgcosθ = gsinθ - a

where;
μk is the coefficient of kinetic friction between the cart and the track
Substitute the given values and calculate coefficient of kinetic friction μk

Therefore, the coefficient of kinetic friction between the cart and the track is 0.114
