Part A - Determining the average force supplied by the jet of compressed air Learning Goal: To be able to use the conservation of energy on a moving body to determine key characteristics about the mechanics of the system. If the package must be moving at a speed of v = 12.5 cm/s when it has reached the distance of 45.0 cm, determine the average force that the jet of compressed air must supply to the package Express your answer to three significant figures and include the appropriate units. A package of mass m = 0.60 kg is pushed across the surface by a jet of compressed air during an assembly-line process. The package is moved through a distance of s = 45.0 cm. The package and the surface are known to have a coefficient of kinetic friction of uk = 0.10. The package is initially at rest for this process. View Available Hint(s) μΑ 圖]?

Part B - Determining the average force supplied by the jet of compressed air for nonzero initial velocity If it is now desired that the package be at rest when it has reached the distance of 45.0 cm , determine the average force that the jet of compressed air must supply to the package if the package is initially traveling in the s direction at a velocity of v = 16.0 cm/s. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) HÅ ]] ? P= Value Units Submit Part C - Determining the average force supplied by the jet of compressed air for a different package If the plant has changed the mass of the package on the assembly line to m = 1.25 kg , determine the average force that the jet of compressed air must supply to the package if the package and surface now have a coefficient of kinetic friction of uk = 0.16. Use the same initial and final conditions as in Part B. Express your answer to three significant figures and include the appropriate units.
