61.When a 3.0-kg block is pushed against a massless spring of force constant constant 4.5×10' N/m, the spring is compressed 8.0 cm. The block is released, and it slides 2.0 m (from the point at which it is released) across a horizontal surface before friction stops it. What is the coefficient of kinetic friction between the block and the surface?
