A first block with m(1)=2.00 kg lies at rest on a frictionless table. An ideal spring, with a spring constant of 100 N/m is attached to the wall and to the block. A second block with m(2)=0.50 kg is placed on top of the first block. The first block is gently pulled to a position x = + A and released from rest. There is a coefficient of static friction of 0.45 between the two blocks. (a) What is the...

2. A 3.80-kg hanging block is pulling against a 2.50-kg block on a tabletop, as shown, via a string over a pulley that is massless and frictionless. At the same time, a constant external force F = 5.50 N is pulling the tabletop block to the right, as shown. There is a static friction coefficient is = 0.75, and kinetic friction coefficient dx = 0.15, with the tabletop. (a) The blocks are initially stationary. With a calculation, determine whether the...

A 4 kg block is stacked on top of an 8 kg block. The blocks are pulled horizontally by a rope attached to the bottom block. The force of the pull is 50 N and the coefficient of kinetic friction between the bottom block and the floor is 0.3. What is the acceleration of the two blocks? What is the minimum static friction coefficient necessary to keep the top block stacked to the bottom block?

Block B, with mass 5.00 kg, rests on block A, with mass 8.00kg. There is no friction between the table and block A, but the coefficient of static friction between block A and B is 0.750. A "massless" string attached to block A passes over a frictionless pulley and block C is suspended from the other end of the string. If we want ALL the blocks moving together with the same acceleration, the largest possible mass that block C can...
