What is the acceleration of the lower crate

Reference no: EM13495484

Two wooden crates rest on top of one another. The smaller top crate has a mass of m1=20kg and the larger bottom crate has a mass of m2=88kg. There is NO friction between the crate and the floor, but the coefficient of static friction between the two crate is museS=0.78 and the coefficient of kinetic friction between the two crate is museK=0.61. A massless rope is attached to the lower crate to pull it horizontally to the right (which should be considered the positive direction for this problem). What is the maximum tension that the lower crate can be pulled at before the upper crate begins to slide. The tension in the rope to 1157N causing the boxes to accelerate faster and the top box to begin sliding. what is the acceleration of the upper crate and as the upper crate slides, what is the acceleration of the lower crate?
