As shown in Figure 3(a), a wooden block B with mass mg 2.4 kg on a rough inclined plane is connected to a massless spring (k 160 N/m) by a massless cord passing over a pulley P of radius R 0.25 m and mass M, 0.60 kg.

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...

Two masses, mA = 34.0 kg and mB = 40.0 kg , are connected by a
rope that hangs over a pulley (as in the figure (Figure 1)). The
center of the pulley is hollowed out so that you may assume all the
mass of the pulley is in the rim. The radius of the pulley is 0.381
m and the mass of the pulley is 3.10 kg . Initially mA is on the
ground and mB rests 2.50 m...

2a. Block A of mass "2m" sits on top of block B of mass "m". There is no friction between block B and the floor, but there is friction between the two blocks. Block B is pulled by a force "F" to the left. Write out the force equations on each block for the case of no slipping between the blocks. Don't solve FA - EFA- EFR = EF= 2b. The pulley (disk) shown has a mass "m" and radius...

1. The two blocks in the figure below are connected by a massless rope that passes over a pulley. The pulley is shaped like a disk (I = MR2). It has diameter of 12 cm and a mass of 4.0 kg. Block A has a mass of 2.0 kg and block B has a mass of 4.0 kg. What is the acceleration of the block A?

In the figure below, two blocks are connected over a pulley. The mass of block A is 32 kg, and the coefficient of kinetic friction between A and the incline is 0.16. Angle θ is 30°. Block A slides down the incline at constant speed. What is the mass of block B? Assume the connecting rope has negligible mass.

By means of a rope whose mass is negligible, two blocks are suspended over a pulley, as the drawing shows, with m1 = 10.7 kg and m2 = 46.0 kg. The pulley can be treated as a uniform, solid, cylindrical disk. The downward acceleration of the 46.0-kg block is observed to be exactly one-half the acceleration due to gravity. Noting that the tension in the rope is not the same on each side of the pulley, find the mass of...

The figure shows two blocks connected by a light cord over a pulley. This apparatus is known as an Atwood's machine. There is no slipping between the cord and the surface of the pulley. The pulley itself has negligible friction and it has a radius of 0.12 m and a mass of 10.3 kg. We can model this pulley as a solid uniform disk. At the instant that the heavier block has descended 1.5 m starting from rest, what is...
