A 4.0 kg box is on a frictionless 35° slope and is connected via a massless string over a massless, frictionless pulley to a hanging 2.0 kg weight a. What is the tension in the string if the 4.0 kg box is held in place, so that it cannot move? b. If the box is then released, which way will it move on the slope? c. What is the tension in the string once the box begins to move?

Two blocks are connected by a string that passes over a massless, frictionless pulley, as shown in the figure. Block A, with a mass mA = 2.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you can solve this exercise entirely using forces and the constant-acceleration equations, but see if you can apply energy ideas instead. Use g = 10 m/s2. When the system is released...

Two masses are connected by a massless string, passing over a massless, frictionless pulley as shown in the diagram. Mass m1 = 5 kg, and is released from rest at a height h = 4 m above the table. Mass m2 = 3 kg, and starts at rest on the table. Ignore friction and air resistance. Take the system to be the two masses and the earth. What is the potential energy of this system, in Joules? Next, you let...
