A block of mass 18 kg and a block of mass 6 kg are attached by a massless string that does not stretch. The string is passed over a massless, frictionless pulley. The blocks are released. The blocks slide against vertical walls as they move, which results in a frictional force of 25N acting on the heavier block and a frictional force of 14N acting on the lighter block.

(a) Determine the magnitude of the acceleration of each block.

__________________________m/s2

(b) Determine the tension in the string.

Two blocks are attached to opposite ends of a string that passes over a massless, frictionless pulley (see the figure). Block ? of mass 10.0 kg lies on a 60.0° incline with a coefficient of friction of 0.500, and block ? of mass 1.00 kg is attached to a vertical spring of force constant 200 N/m. The blocks are initially at rest with the spring at equilibrium. Find the maximum height that the block ? rises.

A block of mass 9.1 kg rests on a horizontal frictionless floor, and is connected to a vertical wall by a spring of force constant 205 N/mN/m as shown in the figure. When the spring is in its equilibrium position (neither stretched nor compressed), the block just touches a second lighter block of mass 3.4 kg at rest on the frictionless floor. The spring is now compressed by 0.12 mm (only the heavier mass is moved towards the wall) and...
