A 115 N block moves on a flat surface at an initial speed of 5 m/s. The coefficient of kinetic friction between the block and the surface is 0.28. The block is 2.2 meters away from the beginning of a spring with a coefficient of 150 N/m. The spring is initially in its stable state and has a length of 140 centimeters.

Show the Work and Energy substituted equation for this case.

You are not required to solve it, but if you want to demonstrate it you can do so
