In the figure below, three ballot boxes are connected by cords, one of which wraps over a pulley having negligible friction on its axle and negligible mass. The masses are m_A = 28.0 kg, m_B = 42.0 kg, m_C = 14.0 kg. When the assembly is released from test, what is the tension in the cord that connects boxes B and C? _______ N How far does box A move in the first 0.290 s(assuming it does not reach the...
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...
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?
Two boxes are connected by a cord running over a pulley. The surface of the table is frictionless. As box B (me -2.47 kg) moves down, box A (ma - 4.6 kg) moves to the right. Find the tension in the cord. Ignore the friction between the cord and pulley. (8 - 9.80 m/s) D Question 5 2 pts Two boxes are connected by a cord running over a pulley. The surface of the table is frictionless. As box B...
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 an arrangement with an air track, in which a cart is connected by a cord to a hanging block. The cart has mass m1 = 0.570 kg, and its center is initially at xy coordinates (-0.490 m, 0 m); the block has mass m2 = 0.510 kg, and its center is initially at xy coordinates (0, -0.140 m). The mass of the cord and pulley are negligible. The cart is released from rest, and both cart and...
Two boxes are connected by a cord running over a pulley. The surface of the table is frictionless. As box B (mB = 2.21 kg) moves down, box A (mA = 4.74 kg) moves to the right. Find the net force acting on box B. Ignore the friction between the cord and pulley. (g = 9.80 m/s2)
Two objects are connected to a cord, and the cord is hung over a pulley connected to the ceiling, as shown in the figure below. m2 The masses of the objects are m1-18.0 kg and m2-10.0 kg, the mass of the pulley is M-5.00 kg, and the radius of the pulley is R = 0.100 m. Object m2 įs initially on the floor, and object m1 is initially 4.30 m above the floor when it is released from rest. The...
Block A in the figure has mass mA = 4.20 kg, and block B has mass mB = 2.40 kg. The coefficient of kinetic friction between block B and the horizontal plane is μk = 0.520. The inclined plane is frictionless and at angle θ = 34.0°. The pulley serves only to change the direction of the cord connecting the blocks. The cord has negligible mass. Find (a) the tension in the cord and (b) the magnitude of the acceleration...
