Homework Statement
A small block is attached to an ideal spring and is moving in SHM on a horizontal, frictionless surface. When the amplitude of the motion is 0.090 m , it takes the block 2.52 sto travel from x= 0.090 m to x= -0.090 m .
If the amplitude is doubled, to 0.180 m , how long does it take the block to travel from x= 0.180 m to x= -0.180 m ?
If the amplitude is doubled, to 0.180 m , how long does it take the block to travel from x= 0.090 m to x= -0.090 m ?

I assume that you will be doing the same thing for the second question as you do for part 1.
I tried to set up a ratio but I think i did it wrong:
0.090m/0.252s = 0.180/t
and got t = 0.504 s but that answer is wrong. I'm not sure what to do with the initial and final displacements.
