A block of mass 1.0 kg. at rest on a horizontal table as show, is attached to two rigid supports by springs A and B. A force of 10.0 N stretches spring A alone by 0.25 m while a force of 2.5 N extends spring B alone by the same amount. Initially the block is at rest between unstretched springs; then it is pushed to the side a distance of 0.50 m, compressing one spring and extending the other. a) What is the total work done to move the block. (TbeblockisheuaLtesLL b) If the block is released, with what velocity does it move through its original equilibrium position? 0) What would be the spring constant of a single spring that would duplicate A and B? A 3.0 kg block is released from rest at the top of a 3.4 m high frictionless incline. At the bottom of the incline, the block encounters a spring with a constant of 4.0 x 102 N/m on a horizontal surface. The coefcient of friction between the block and the horizontal surface is 0.20. How far does the block slide while compressing the spring
