A block of mass m is oscillating with a spring of stiffness k. See the picture.In order to increase its amplitude, one of end of the spring (point A) is suddenly moved with a velocity v to the left and kept moving with that velocity.
Determine when it should be suddenly moved in order to maximize its amplitude!
How's the result if it's not suddenly moved, but accelerated by a to the left!

this question is from some book or u made it ??
may i know about some gud books in physics . where i can find questions of the same level as u're giving here . i want to improve my physics .
looking forward for ur reply .

If I write a book's title or author, it means I adopt it from the book. But until now I haven't adopted any problem from books.
Maybe later I can show the physics books I recommended as a gadget of this blog.
