Homework Statement
A 2.0 kg block is released from rest on a frictionless 30 degree incline. After sliding 0.80 m it comes in contact with the spring, and after sliding an additional 0.20 m, it comes momentarily to rest. What is the spring constant?
I knew that spring constant is equal to the force it takes to compress a spring over the distance the spring compresses. I thought that the force would just be mg which is 2.0x9.8=19.6, and I just divided that value by 0.20 to get 98 N/m, but my teacher told me that that isn't the correct answer...
