Leilani loads luggage into a Hawaiian Air passenger plane bound for Vegas using a conveyor belt tilted at an angle of 20.0o . She places a few pieces of luggage onto the belt before it starts to move. When she turns the belt on it takes 0.70 s for it to reach a top speed of 1.2 m/s. Does the luggage slip? Assume µs = 0.50 between the luggage and the belt

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
