Just wondering DEvens, what equation did you use to get the same answer as I did?

That's what I was thinking. I don't know how else to find velocity other than these two methods, which seem correct. I will try and rerecord some data when I get back in the lab again. The velocity was recorded with a calibrated motion sensor. I can upload logger pro data if you want, too. Let...

Sorry if it's a little confusing. The length of the spring under zero tension is .085m, h is the height from the pivot point of the top of the spring to the cart. Delta Xf is the distance in zero tension of the bottom of the spring to stretched position on the cart once at 90 degrees. And yes...

I have to find the velocity of the cart when it lands right under the spring at 90 degrees. The spring is at an angle. I am not getting the right numbers though, can anyone help? This is my first post here BTW. This community looks awesome! 2. Equations You can use anything, but I used both...
