A block of mass 12.0 kg slides from rest down a frictionless 34.0° incline and is stopped by a strong spring with k = 1.0 104 N/m. The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?
