A spring with a spring constant of 2.4 N/cm is compressed 20 cm and released. The 8 kg mass skids down the frictional incline of height 27cm and inclined at a 19 degree angle. The acceleration of gravity is 9.8 m/s2.
The path is frictionless except for a distance of 0.6m along the incline which has a coefficient of friction of 0.5.
What is the final velocity of the mass ? Answer in units of m/s

The two fields of chemical traction enter these questions.
A NON-magnetized material would be .3 times the equation
plus 2.4 for the averages of material molecule speed 3.11mph.
If the material is a material specific like gold, it could be 3.6mph.
