A spring with a spring- constant 3.4N/ cm is compressed 29cm and released. The 2 kg mass skids down the frictional incline of height 50 cm and inclined at 21 degrees angle.
The acceleration of gravity is 9.8 m/s^2.
The path is frictionless except for a distance of .07 m along the incline which has a coefficient of friction of 0.5.
I am kind of completely lost.
The Attempt at a Solution
so far this is what I have but its probably wrong anyway
N= (2)(9.8)= 19.6
Friction= (19.6)(0.5)= 9.8
Total Energy= 24.097
Problem attached its #6..
