The work W required to lift an object varies jointly with the object’s mass m and the height h that the object is lifted. a. Write an equation which utilizes the constant of proportionality, k, to represent the given situation. This equation will contain four variables.
b. Suppose the work required to lift a 110-kilogram object 1.5 meters is 2120 joules. Use this information along with the result from part a) to find the constant of proportionality, k.
c. Write a working equation which looks like part a) but includes the constant of proportionality you found in part b).
d. Use the result from part c) to determine the amount of work required to life a 150-kilogram object 1.2 meters.
