A spring with a spring-constant 3.4 N/cm
is compressed 27 cm and released. The 9 kg
mass skids down the frictional incline of height
13 cm and inclined at a 17◦ angle.
The acceleration of gravity is 9.8 m/s2 .
The path is frictionless except for a dis-
tance of 0.5 m along the incline which has a
coefficient of friction of 0.2.
What is the final velocity vf of the mass?
