“A wooden crate weighing 150 N is resting on a horizontal surface. If the coefficient of static friction between the crate and the surface is 0.5, calculate the maximum static friction force that can act on the crate. Show all work. A suitcase with a weight of 80 N is placed on a flat surface. If the coefficient of static friction between the suitcase and the surface is 0.6, determine the maximum static friction force acting on the suitcase. Show all work.”
