Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other by a string that passes through a massless pulley. The stiffness constant of the spring attached to m1 and the wall is k=120N/m and the coefficient of kinetic friction between m1 and the surface is given to be μk=0.2. If the system is released from rest when the spring is at its equilibrium length and m2 is at a...

Classical Mechanics ! UD ︶ Two blocks of mass m1 and m2, respectively are connected by springs in the following way: mi m2 where on the very left there is a solid wall that does not move. As indicated in the picture, the displacement from the equilibrium position of blocks 1 and 2 is x1 and x2, respectively. Each spring exerts a force of F =-kx, where lxl is the displacement.

Blocks A (mass 2kg), B(mass 5 kg), and C (mass 15 kg) are connected by two cables as shown. The system is released from rest. First show that the blocks will move (hint: right at the limit of static equilibrium, A is about to move up, B to the right, and C'down), then find the acceleration of the blocks and the tensions in the cables. The coefficient of static and kinetic friction between block B and the surface are both...

Two blocks of masses 24 kg and 9 kg are connected together by a light string and rest on a frictionless level surface. Attached to the 9-kg mass is another light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.6 m/s2 what is the tension in the connecting string between the blocks?

Two blocks with equal mass m = 2.1 kg are connected by a string that passes over a pulley wheel. Block A sits on a level table, with friction acting between the block and ramp surfaces with coefficient of kinetic friction µk = 0.27. Block B is suspended below the pulley wheel, initially at a height h = 1.23 m above the ground. The system is released from rest. What is the final speed of both blocks in units of...
