A 2.00-kg package is released ona 53.1o incline, 4.00 m from a longspring with force constant 120 n/m that is attached at the bottom of the incline . The coefficients of friction between the package and the incline are static frictionis 0.4 and kinetic friction is 0.2. The mass of the spring is negligible.
What is the speed of the package before it reaches the spring?
What is the maximum compression of the spring?
The package rebounds back up the incline. How close does it get to its initial position?
