Can you help me with General Physics: Mechanics of Solids and Fluids?

Please PleasePlease---> **Use equations from the equation sheet and follow the procedure done in the lecture.**

l. A super-spring has a force equation given by F; = 405:? , where F is in N and x is in In. Find the work done by the spring if it starts with a stretch of l cm and ends with a compression of 15.1} cm. You will need to integrate the force equation since this is not a Hooke's Law spring. Use equations from the equation sheet and follow the procedure done in lecture. _ _ _ a _ 2. The force on an atom in a crystal structure is given by F = _J, , where a is a I constant and x is its distance from an adjacent molecule. The atom starts at so = A and moves to an unknown i'nial location of xf, where xJ-s D. If the work done by the force during this motion is W= -E , find If. Use equations from the EA\" equation sheet and follow the procedure done in lecture
