Needed quadratic formula: (gsintheta+sqrt(((gsintheta)^2)+(k/m)(v^2+2sintheta*d))/(k/m) gives .1238, the correct answer

Since all of you don't know how to do it I am going to just look up the answer.

I need help

Does anyone know how to do the problem?

Maybe there isn't a bug. Hmm I am very confused

Units are already included and I substituted dsin(theta) for h

Most likely there is a bug in the homework grading system. .084 is correct.

OK, like I said I got x=.084. Basically I have that KE (initial energy) + Gravitational PE is equal to the Work the spring does and solved for x. What did I do wrong?

Picture of problem

An inclined plane of angle θ = 20.0° has a spring of force constant k = 525 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.31 kg is placed on the plane at a distance d = 0.312 m from the spring. From this...
