A 40-kg package is at rest on an incline when a force P is applied to it.
Question:
A 40-kg package is at rest on an incline when a force P is applied to it. Determine the magnitude of P if 4 s is required for the package to travel 10 m up the incline. The static and kinetic coefficients of friction between the package and the incline are 0.30 and 0.25,respectively.
