(a)
Tension between AC is T1 and BC is T2 .
14(9.80) - T2 = 14a
T2 + 40(9.8) - T1 = 40a
T1 = 28a
T2 + 392 - 28a = 40a
T2 + 392 = 68a
T2 = 68a - 392
137.2 - (68a - 392) = 14a
529.2 = 82a
a = 6.453 m/s²
T2 = 46.85 N
b)
a = 6.453 m/s² ( Approx )
s = ½at²
s = ½(6.453)(0.290)²
s = 0.271 m

In the figure here three ballot boxes are connected by cords, one of which wraps over a plley having negligible friction on its axle and negligible mass. The masses are mA-34 kg, mp is released from rest, (a) what is the tension in the cord connecting B and C, and (b) how far does A move in the first 0.250 s (assuming it does not reach the pulley)? 43 kg, and mc-13 kg. When the assembly (a) Number (b) Number...
I HAVE the answer (B) but i dont know how to get it, please explain. my professor wrote down a bunch of equations but i dont understand them, please explain in words as if i were stupid. i have attached the sheet of notes he wrote on this problem to make your life much easier, you dont really have to solve anything, as the answers are right here, all you have to do is literally explain to me how these...
Two boxes are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below.The masses of the boxes are m1=18.0 kg and m2=12.0 kg, the mass of the pulley is M=5.00 kg, and the radius of the pulley is R=0.300 m. Box m2 is initially on the floor, and box m1 is initially 4.70 m above the floor when it is released from rest. The pulley's axis has negligible...
The figure shows three blocks attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table; the masses are mA = 4.40 kg, mB = 8.30 kg, and mC = 13.0 kg. When the blocks are released, what is the tension in the cord at the right?

The two blocks in the figure(Figure 1) are connected by a massless rope that passes over a pulley. The pulley is 14 cm in diameter and has a mass of 3.0 kg As the pulley turns, friction at the axle exerts a torque of magnitude 0.53 N.m. Part A If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor?
The two blocks in the figure Figure 1) are connected by a massless rope that passes over a pulley. The pulley is 14 cm In diameter and has a mass of 2.1 kg. As the pulley turns, friction at the axle exerts a torque of magnitude 0.52 N·m. Part A If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor?
