You compress a block on a spring. The spring has a constant k = 3000 N/m and the block has a mass of 4 kg. You compress the spring 0.3 m and release the block. After being released, the block hits a rough surface with a coefficient of friction of 0.6. How far does the block travel across the rough surface before it comes to a stop? Please use the correct formulas for this question so I can understand.

A spring of spring constant k=261 N/m is attached to a block of mass 1.38 kg and stretched horizontally to a position 15.0 cm from the springs equilibrium position. The spring and mass are released and oscillate in simple harmonic motion across a frictionless horizontal surface. What is the maximum speed obtained by the mass? m/s

You attach one end of a spring with a force constant k = 693 N/m to a wall and the other end to a mass m = 1.62 kg and set the mass-spring system into oscillation on a horizontal frictionless surface as shown in the figure. To put the system into oscillation, you pull the block to a position xi = 6.76 cm from equilibrium and release it. A horizontal spring labeled k is attached on its left end to...
