Consider again the crates in Problem 45, but now assume the rope has a mass of 2
Question:
Consider again the crates in Problem 45, but now assume the rope has a mass of 2 kg. If the tops of the crates start at the same initial height and the rope has a length of 10 m, what is the final speed after the crates have moved a distance of 2.5 m?
Data From Problem 45
Two crates of mass m1 = 40 kg and m2 = 15 kg are connected by a mass less rope that passes over a mass less, friction less pulley as shown in Figure P6.45. The crates start from rest.
