A 2.4 kg block is placed against a spring on a frictionless 17o incline. The spring, whose spring constant is 59.2 N/cm , is compressed 35.3 cm and then released.
What is the elastic potential energy of the compressed spring in J?
According to my calculations and my book, the potential energy of a spring is .5kx2. That didn't work, so I converted cm to m in k and x. That didn't work either. The only difference between this problem and a similar one in the book is that this spring is at an angle. Could someone give me a hint as to what the trick with this problem is?
