When being unloaded from a moving truck, a 16.0- kilogram suitcase is placed on a flat ramp inclined at 40.0 o. when released from rest, the suitcase accelerates down the ramp at 1.36 m/s². what is the coefficient of kinetic friction between the suitcase and the ramp?

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
