1. The problem statement, all variables and given/known data A 2.0 kg package is released on a 53.1◦ incline, 4.0 m from a long spring with force constant 120 N/m that is attached at the bottom of the incline. The coefficient of friction between the package and the incline are µs=0.40 and µk=0.20. The mass of the spring is negligible. a. Show that the maximum compression of the spring is 1.06m. b. The package rebounds back up the incline. Show that the package comes to rest at a distance 1.32 m below its initial position. 3. The attempt at a solution I want to use that K_1 + U_1 + W_other = K_2 + U_2 W_other in this case is the work of friction and the work of the spring?
