A Baggage Handler Drops Your Suitcase Another Physics Problem Friction?

Another physics problem friction? - a baggage handler drops your suitcase

A drop of 9.40 Baggage handler his suitcase on a treadmill running at 1.80. The materials are such that = = 0.430 and 0.290.

How far is your suitcase dragged before it surfs smoothly on the tape?

The friction of your luggage will be accelerated from zero to the speed equal to the speed of the belt. Thus we have

En = N = mg = ma UD UD

In addition, the acceleration is

a = g ud

Node where the coefficient of dynamic friction. How long does it take to reach the belt speed is

t = a / VF

If the initial velocity is zero and the last is the speed of the tape. The distance is determined by the basic kinematic equation

d = 1 / 2 ^ 2

Well, you have all the information that you use the computer.
