Two wooden crates rest on top of one another. The smaller top crate has a mass of m1 = 20 kg and the larger bottom crate has a mass of m2 = 86 kg. There is NO friction between the crate and the floor, but the coefficient of kinetic friction between the two crates is μk = 0.68. 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).
1)The rope is pulled with a tension T = 371 N (which is small enough that the top crate will not slide). What is the acceleration of the top crate?
