A block A with a mass of 3 kg rests on a horizontal table top. The coefficient of kinetic friction, μk = 0.5. A horizontal string is attached to A and passes over a massless, frictionless pulley, and block B with mass 2 kg hangs from it. Because of the pull of gravity, the masses accelerate. What is the Tension in the string (in Newtons)?

    A wooden block with mass 0.37 kg rests on a horizontal table, connected to a string that hangs vertically over a friction-less pulley on the table's edge. From the other end of the string hangs a 0.12 kg mass. What minimum coefficient of static friction μ s between the block and table will keep the system at rest? Find the block's acceleration if μ k =0.20.

    Block A has a mass of 20 kg and rests on a frictionless table. A cord attached to block A extends horizontally to a pulley at the edge of the table, block B has a 10 kg mass and hangs over the edge attached to the string. How would I calculate the tension in the cord?

  • A block of mass m1= 4.00 kg moves on the surface of a horizontal table. The...

    A block of mass m1= 4.00 kg moves on the surface of a horizontal table. The coefficient of kinetic friction k between the table top and m1 is equal to 0.350. Block 2 of mass m2= 2.00 kg is tied to m1 via a string that passes over a frictionless, massless pulley. The two blocks start from rest and m2 drops by a distance L =1.75 m to the floor. Use the work-energy theorem to determine the speed v of...

    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...

    A block of mass m1 = 36 kg on a horizontal surface is connected to a mass m2 = 23.0 kg that hangs vertically as shown in the figure below. The two blocks are connected by a string of negligible mass passing over a frictionless pulley. The coefficient of kinetic friction between m1 and the horizontal surface is 0.30. (Assume gravity acts toward the +ydirection and the +x-axis is parallel to the surface and to the right.) (a) What is...

    Block B, with mass 5.00 kg, rests on block A, with mass 8.00kg. There is no friction between the table and block A, but the coefficient of static friction between block A and B is 0.750. A "massless" string attached to block A passes over a frictionless pulley and block C is suspended from the other end of the string. If we want ALL the blocks moving together with the same acceleration, the largest possible mass that block C can...

    A block of mass m1- 8.2 kg is at rest on a plane that makes an angle of 9 30° above the horizontal. The coefficient of kinetic friction between the block and the plane is k-0.100. The block is attached to a second block of mass m2- 17.8 kg that hangs freely by a string that passes over a frictionless, massless pulley (see the Figure). Calculate the speed when the second block has fallen 9.7 m. (Your result must contain...
