A spring (oriented horizontally, k = 40 N/m) is attached to the left side wall in a room whose floor is frictionless. A small, dense mass (m = 0.5 kg), at rest on the floor, is attached to the right side of the spring. The unelongated spring length is 0.6 m. A person then begins to pull on the system to the right with an applied force of 20 N. This force is applied until the spring elongates by 0.25 m. The force then instantly disappears. Find the speed of the block when the applied force vanishes. A. 2.9 m/s B. 3.9 m/s C. 4.9 m/s D. 5.9 m/s

A light rope is attached to a block with mass 4.00 kg that restson a frictionless, horizontal surface. The horizontal rope passes overa frictionless, massless pulley, and a block with mass m is suspendedfrom the other end. When the blocks are released, the tension in therope is 15.0 N. How does the tension compare to the weight of the hanging block?
