Question

Calculate the instant net force exerted on the package at its lowest point. Using the general energy equation for the motion of the package between the lowest and the final points, find how close the package is to its original position. Calculate the change in internal energy for the package’s trip down and back up the incline.

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 1.10 × 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
Luk = 0.200. The mass of the spring is negligible. (a)
