3) An object of mass of 4.0 kg traveling at 2.0 m/s along a horizontal plane hits a relaxed spring of spring constant 400 N/m. The maximum spring compression is 0.15 m. V = 2.0 m/s a) Determine the thermal energy (16) m = 4.0 kg dissipated by friction as the object compresses the spring. V = 0 MA x=0 x=0.15 m X (6) b) What is the friction force between the block and the horizontal surface? Assume the thermal energy dissipated by friction is 2.0 J if you did not solve a). (10) c) How far would the object compress the spring in the absence of friction
