m. o wooden crates rest on top of one another. The smaller top crate has a mass of m, = 18 kg and the larger bottom ate has a mass of m2 = 85 kg. There is NO friction between the crate and the floor, but the coefficient of static friction tween the two crates is µ̟ = 0.82 and the coefficient of kinetic friction between the two crates is pk = 0.66. A massless pe is attached to the lower crate to pull it horizontally to the right (which should be considered the positive direction r this problem). The rope is pulled with a tension T= 398 N (which is small enough that the top crate will not slide). What is the acceleration of the small crate?

Question
m, m2 Two wooden crates rest on top of one another. The smaller top crate has a mass of m, = 18 kg and the larger bottom crate has a mass of m2 = 85 kg. There is NO friction between the crate and the floor, but the coefficient of static friction between the two crates is µ; = 0.82 and the coefficient of kinetic friction between the two crates is Hk = 0.66. 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 = 398 N (which is small enough that the top crate will not slide). What is the acceleration of the small crate? m/s Submit You currently have 0 submissions for this question. Only 5 submission are allowed. You can make 5 more submissions for this question. 2) In the previous situation, what is the frictional force the lower crate exerts on the upper crate? N Submit You currently have O submissions for this question. Only 5 submission are allowed. You can make 5 more submissions for this question. 3) What is the maximum tension that the lower crate can be pulled at before the upper crate begins to slide? N Submit You currently have O submissions for this question. Only 5 submission are allowed. You can make 5 more submissions for this question. 4) The tension is increased in the rope to 1168 N causing the boxes to accelerate faster and the top box to begin sliding. What is the acceleration of the upper crate? m/s? Submit You currently have 0 submissions for this question. Only 5 submission are allowed. You can make 5 more submissions for this question. 5) As the upper crate slides, what is the acceleration of the lower crate? m/s Submit You currently have O submissions for this question.
