Hi, I Need to know exactly how to solve this...I just can't take it anymore. The only reason I'm so into it now is because I don't get it. I promised my girlfriend I would help her and now she's annoyed because I get more into it than she does. But anyway, someone..PLEASE tell me what has to be done here. I'm sure its something simple but I have no more brain power to even remotely try.
Two blocks, each with a mass 0.40 kg, can slide without friction on a horizontal surface. Initially, block 1 is in motion with a speed v = 1.2 m/s; block 2 is at rest. When block 1 collides with block 2, a spring bumper on block 1 is compressed. Maximum compression of the spring occurs when the two blocks move with the same speed, v/2 = 0.60 m/s.
If the maximum compression of the spring is 1.9 cm, what is its force constant?
I came up with 111N/m but only because I followed a patern, didn't feel like I knew what I was doing...is that right? 111?
