Draw a free-body diagram for the package as it is sliding back up the incline while in contact with the spring. Draw the vectors starting at the black dot. The orientation of the vectors will be graded. The length of the vectors will not be graded.
A package of mass m = 2.00 kg is released on a 53.1° incline, a distance D = 5.00 m from a long spring with force constant 1.30 × 102 N/m that is attached at the bottom of the incline (Figure 1). The coefficients of friction between the package and incline are μs = 0.400 and μk = 0.000.
(a) What is the maximum compression of the spring?
(b) The spring force, the spring force, the kinetic friction force, and the normal force - how close does it get to its original position?
(c) What is the change in the internal energy of the package and incline from the point at which the package is released until it rebounds to its maximum height?
