A 2kg package is released on a 53.1 degree incline, 4m from a long spring with force constant 120 n/m that is attached to the bottom of the incline. The surface of the incline applies a constant 11.5N frictional force to the package. The mass of the spring is negligible.
What is the speed of the package just as 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?
