1. The problem statement, all variables and given/known data I've been trying to answer a Physics-based question, and I can't seem to correctly answer the problem correctly. it is a five-part problem, and since I cannot answer the first problem correctly, the other four cannot be answered. It is... The block in the figure below lies on a horizontal frictionless surface and is attached to the free end of the spring, with a spring constant of 35 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 3.2 N pulls the block in the positive direction of the x axis, stretching the spring until the block stops. Assume that the stopping point is reached. (a) What is the position of the block? (b) What is the work that has been done on the block by the applied force? (c) What is the work that has been done on the block by the spring force? I also need to find answers to these questions with regards to: 'during the block's displacement.' (d) The block's position when its kinetic energy is maximum (e) The value of that maximum kinetic energy. 2. Relevant equations This particular problem utilizes Hooke's law and Work/Kinetic energy theorems. so far the only one I've used was Hooke's Law [itex] F = kx[/itex] I'm aware that I will need to use work equations to solve for b and c W = .5kxi2 - .5kxf2 As for d and e, I've not a clue how to answer. 3. The attempt at a solution When solving for part a, I simply manipulated Hooke's Law to solve using the aforementioned values (3.2N and 35N/M). I ended up getting 0.0914 meters, but it is considered incorrect. Am I missing something in the equation?
