the angle is 39o but are you saying for the first equation where i use F=kx, i should use (580+0)/2 for the value of k instead of just 580?

A spring is mounted at an angle of theta = 39degrees on a frictionless incline as illustrated in the figure below. The spring is compressed to 15 cm where it is allowed to propel a mass of 4.9 kg up the incline. (a) If the spring constant is 580 N/m, how fast is the mass moving when leaves...
