PUSHING BLOCKS
You exert a 238 N push the leftmost of two identical blocks of mass 209 g connected by a spring of stiffness 554 kg/s2. After pushing the block a distance 15 cm, you release it; by this time the rightmost block has moved a distance 5 cm.
(a) What is the energy in the oscillations between the blocks?
(b) What is the speed of the center of mass after the push?
(c) What is the initial relative speed between the blocks?
(d) What is the amplitude of the oscillation?
(e) What are the fastest as slowest linear speeds of the blocks?
Fastest:___

Consider the following three cases 1. The finger is pushing but not hard enough. Neither block moves 2. The finger is pushing hard enough that the two blocks are speeding up 3. The blodies have sped up, and are now moving at a constant speed. The finger still has to push to keep them going at a constant velodty. In all cases where the blocks are moving, they are moving together. (Block is not sliding on block A.) Block A...

Two blocks of mass m1 300 g and m2- 725 g are pushed by a force. The coefficient of kinetic friction between each block and the ground is 0.4. The blocks move together (with one pushing the other) with an acceleration of 225 cm/s. What is the value of the applied force in Newtons? Hint:Make sure to include the frictional force for each block.

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...

6. Consider a horizontal spring with spring constant k. A block with mass m is pushed far to the left against the spring until the spring is compressed a distance r relative to its relaxed length. A second block, which is stationary and also has a mass m, is located to the right of the spring im rrm a) We release the first block from rest. Due to the force from the spring, it slides to the right and eventually...

1. Three blocks with masses m1 = 5.00 kg, m 2 = 10.0 kg, and ,n3 15.0 kg are connected by massless strings which run over two frictionless pulleys. Block 1 sits on a highly polished plane inclined at an angle θ-30.0° above the horizontal. The coefficient of friction between block 1 and the plane is μk1 = 0.200, Block 2 sits on a horizontal surface and the coefficient of friction between block 2 and the surface is Alk2 =...

Your answer is partially correct. Try again. Two identical 0.12 kg blocks (labeled 1 and 2) are initially at rest on a nearly frictionless surface, connected by an unstretched spring, as shown in the upper diagram, where x2 = 0.05 m. Then a constant force of 7 N to the right is applied to block 2, and at a later time the blocks are in the new positions shown in the lower diagram, where xi = 0.02 m and x3...
