Problem#2 You work for a moving company are forced to pull two crates along the floor as shown in the figure below.in The two crates are connected by a very light rope (it's mass is much smaller than that of either block). You want to get done as soon as possible and pull as hard as you possibly can and manage to maintain a pulling force of F = 600.0 N. As a result the crates are moving with an unknown constant acceleration a. Their masses are mi = 50.0 kg and m2 = 20.0 kg, and the coefficient of kinetic friction between each crate and the floor is Uk = 0.300. g= 9.81 m/s² %3! m1 m2 F a) Find the magnitude of the acceleration a of the two crates. b) Find the magnitude of the tension T on the rope connecting the two crates to each other. For this problem especially, it will be helpful to refrain from using numbers until you have an algebraic expression for T.

3. Here is a problem that beautifully illustrates why we want this new approach. Problem: A mass of 3 kg is placed on a 600 that has a coefficient of 0.2. (Since the mass will be moving this is kinetic friction...) What is the resulting acceleration of the mass? The mass will then travel down the incline for 0.5 m until it reaches the bottom of the incline. How fast will the mass be traveling at the bottom of the incline? The mass will then slide across the floor (which is level). How far will it slide before coming to rest?

3) So, James makes it to the other side, but obviously doesn’t catch Kevin. He decides to go back to the lab and test some other ideas. One involves pulleys, rope, and blocks. He sets up a system of pulleys as shown. The coefficient of kinetic friction on the table is 0.12. a) What is the acceleration of the three objects? b) What is the tension in each of the two strings?
