1. An object with m = 2.6 kg is on top of a hill and is pressed against spring with k = 300 N/m. The spring is compressed by x = 0.55 m. The hill is 2.5 m high. The object is released and after the spring is decompressed it slides down the hill to the bottom. It does experience riction which does work of W = -92 J. At the bottom of the hill what is the object's kinetic nergy and what is its velocity? %3D %3D
