A 4.65 kg block is launched horizontally by a spring with constant k = 2,584.6 N/m. It slides across a horizontal surface. The spring was initially compressed 22 cm. After sliding awhile, the block hits a rough patch and then glides forever after with speed 2.4 m/s. How much work was done by friction in the rough patch?
