Question

i am truly stuck on this problem it's two parts but I know I solved the first part correctly. the question is as follows: Find the periods of block 1& block 2 given k= 50.3N/m and m=1.21kg. (Assume the springs are compressible and can stretch.)
the first image (block 1)is of a mass with 2 springs (connected on a stationary wall) on the same side of mass.
the second image (with block 2) has two springs total, one on both opposing sides of the block.
***************
i was able to conceptualize the first image using 2?/T=?(k/m), but since the 2 springs are on the same side of it would be 2?=?(2k/m)
i am completely lost with the second image i feel as if i am not accounting for all variables to find the period plz help me
(asked prior but the site is not allowing me to rate or comment the response.)

But my comment pertaining to the prior expert is as follows:
I do appreciate the quick the response, but as I had previously stated before I need some additional help to considering the additional variables that makes image 2 period different from image 1. For the first image I calculated 0.6891 s, for the period of image 1. I would expect the period for image 2 to be significantly lower since the opposing spring is also repressing the system. So, i guess i feel as if the response was great for part 1one (which I had solved prior to posting the question for help), but not the second(image2) part- which is the part I needed help with. If it could be further elaborated I would be most appreciative

Explanation / Answer

sol An equation to find period is: T = (2p)(vm/k) An additional question that I have: A prior question asks: Choose the best explanation among the following: I. Springs in parallel are stiffer than springs in series; therefore the period of block 1 is smaller than the period of block 2. II. The two blocks experience the same restoring force for a given displacement from equilibrium, and hence they have equal periods of oscillation. III. The force of the two springs on block 2 partially cancel one another, leading to a longer period of oscillation.
