A system composed of blocks, a light frictionless pulley, and connecting ropes is shown in the figure. The coefficient of friction between the both blocks and the incline is 0.12. The 9.0-kg block accelerates downward when the system is released from rest. What is the acceleration of the system and the tension in the rope connecting the 6.0-kg block and the 4.0-kg block?

Expert Solution

Two blocks are connected by a light string that passes over a frictionless pulley having a moment of inertia of 0.0040 kg*m2 and a radius of 5.0 cm. The coefficient of kinetic friction between the table top and the upper block is 0.300. The blocks are released from rest. Using energy methods, find the speed of the upper block just as it has moved 0.600 m.

Two masses are connected by a light string, which passes over a frictionless pulley as shown in fig .3 on a the chalkboard. The inclined plane is rough. When m1=10kg , m2 = 3.0 kg and theta = 60degrees, the 10 kg mass moves down the inclined plane and accelerates down the nclined pane at a rate of 2.0m/s^2. Find a) the tension in the string. b)the coefficient of kinetic friction between the 10 kg mass and the inclined plane.

Three blocks of unknown mass m1, m2=2.0 kg, and m3 = 3.0 kg are on a frictionless horizontal surface as shown on the figure below.

Three blocks of unknown mass m1, m2=2.0 kg, and m3 = 3.0 kg are on a frictionless horizontal surface as shown on the figure below. The blocks are connected by ideal, massless strings. A force FL=11 N is applied to the left block and is directed to the left. A force FR=33 N is applied to the right block, and is directed to the right. The tension T12 in the string between m1 and m2 is 13 N and the...

Two blocks are free to slide along the frictionless wooden track shown below. The block of mass m1 = 5.07 kg is released from the position shown, at height h = 5.00 m above the flat part of the track. Protruding from its front end is the north pole of a strong magnet, which repels the north pole of an identical magnet embedded in the back end of the block of mass m2 = 10.3 kg, initially at rest.
