Road Runner's revenge.  Wile E. Coyote is on the vertical front of a train that is accelerating. He is not standing on anything and is not holding on to anything. He is being held up solely by the frictional force between him and the front of the accelerating train. Coyote has a mass of 18.0 kg, and the coefficient of static friction is 0.20 for this situation. Determine the minimum acceleration required for the coyote to not slip down the front of the train
