A 50.0-kg block and a 100.0-kg weight are connected with a rope, passing over a pulley as shown in the picture. The 50.0-kg block is on a surface with a coefficient of friction of mu_k = 0.50. The pulley is a solid disc whose radius is 0.20 m and whose rotational inertia is 2.0 kg m^2. The rope does not stretch or slip. When released from rest, what is the acceleration of the system?
Two boxes connected by a light horizontal rope are on a horizontal surface, as shown in the following figure. The coefficient of kinetic friction between each box and the surface is 0.30. One box (box B) has mass 4.84 kg , and the other box (box A) has mass m . A force F with magnitude 37.3 N and direction 53.1 ∘ above the horizontal is applied to the 4.84 kg box, and both boxes move to the right with...
Two blocks, each of mass m = 6.90 kg , are connected by a massless rope and start sliding down a slope of incline θ = 40.0 ∘ at t=0.000 s. The slope's top portion is a rough surface whose coefficient of kinetic friction is μk = 0.350. At a distance d = 2.90 m from block A's initial position the slope becomes frictionless. What is the velocity of the blocks 4.10 s after the blocks have started moving? Assume...
(a) As shown in Figure 4(a), a wooden block A with mass ma = 2.4 kg on a rough inclined plane is connected to a massless spring (k = 160 N/m) fixed to the top of the inclined plane. The angle of the inclined plane is @ = 37º and the coefficient of kinetic friction is uk = 0.30. The other end of block A is connected to block B via a massless cord passing over a pulley P of...

Figure 5-47 Problems 51 53 In Fig. 5-48, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T 65.0 N. If m 12.0 kg m 24.0 kg, and m 31.0 kg,calculate (a) the magnitude...
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. The angle of the inclined plane is 0 37 and the coefficients of static and kinetic frictions are g 0.35 and A 0.30 respectively The frictional force at the axle of the pulley...
