Answer:
0.65812
Explanation:
m = Mass of suitcase = 16 kg
= Incline angle = 40°
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration of the block = 1.36 m/s²
f = Frictional force
The normal force is given by

In x direction

Frictional force is given by

The coefficient of kinetic friction between the suitcase and the ramp is 0.65812
