Solve for the following problems (please answer 4-5)
4. A man carries a 50 - kg package from the ground floor to the third floor of a building, a vertical distance of 15
m. Upon reaching the third floor, he pushes the package through distance of 3.5 m by a force of 950 N applied
30° with the horizontal. Find the work done by the man.
5. An object with a mass of 5.13 kg placed on top of a spring compresses it by 0.25 m.
a) What is the force constant of the spring?
b) How high will this object go when the spring releases its energy?
