3. A ramp leads up to a level area and then has a vertical drop off at the far end. The tilted ramp part is at an angle of 3010f to the horizontal There are 3 masses involved: one on the tilted ramp (mass#] is # 20kg), one on the level area(mass#2 is 5.65kg), and one suspended freely by a rope across a frictionless pulley off the far end of the structure (mass#3 is 3 /3kg). Each mass is connected to the next one by a piece of massless strong rope, There is an additional pulley where the tilted area turns into a horizontal level area. The two ropes involved are strong enough to handle any tension that arises in them from the accelerating system of masses. There is a small kinetic friction coefficient of 0.125 between the first two masses on the ramp and the raised level areal Assume that the system is already slightly moving, just enough to avoid static friction concerns (this has no other effect on this problem) Draw a labelled free body diagram (FBD) for each of the 3 masses and use them to write out the net force equation for each mass. It might help to first read through parts (a) to (c) below in order to help you clarify what the 3 unknown variables are that mathematically link the equations you determined from the three FBD's. By solving this system of equations you should be able to determine the correct quantities for each of the unknowns asked for in parts (a) to (c) below: (a) What is the acceleration of this system? (b) What is the tension in the rope between the mass=] on the ramp and mass#2 on the raised level area? (c) What is the tension in the rope between the mass#2 on the level area and mass#3 that his hanging in midair off the far right hand vertical drop-off of this structure
