In the figure, two 6.20 kg blocks are connected by a massless string over a pulley of radius 2.40 cm and rotational inertia of 7.40 Times 10^-1 kg m^2. The string does not slip on the pulley; and there is no friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest the pulley turns through 1.30 rad in 91.0 ms and the acceleration of the blocks is constant. What are...

Two blocks are connected by a massless rope slung over a massless, frictionless pulley at the edge of a table. One block moves horizontally along the tabletop; it has a mass of 8.00 kg. The other block is freely-hanging off the edge of the pulley; it has a mass of 6.00 kg. Initially, both blocks have a speed of 0.900 m/s; the blocks come to rest after they have moved 2.00 m. What is the coefficient of kinetic friction between...

Two blocks are connected by a massless rope.
Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1=13.75 kg is on a horizontal table and the other block with mass m2=6.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. Part (a) Assuming friction forces are negligible, write an expression, using only the variables provided, for the acceleration that the block of mass...
