It takes 500 j of work to compress a spring 10 cm. what is the force constant of the spring? (b) when a 3.0 kg block is pushed against a massless spring of force 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?
