A 1.34-kg block sliding on a horizontal surface collides with a spring of force constant 1.93 N/cm. The block compresses the spring 4.16 cm from the un-extended position. Friction between the block and the surface dissipates 117 mJ of mechanical energy as the block is brought to rest. Find the speed of the block at the instant of collision with the spring.
