Find the amount of work required to lift a 100-kilogram object 1.5 meters.

Answer to Problem 70E
The amount of work required to lift a 100-kilogram object 1.5 meters is 1470 joules
Explanation of Solution
Given:
Work done W in lifting an object depends upon mass m to be lift and height h to be liftedExplanation:
Work done W in lifting an object depends upon mass m to be lift and height h to be lifted. Let's calculate a formula calculating constant of proportionality using the fact 2116.8 joules of work has been done while lifting an object of 120 kilograms to a height of 1.8 meter. Finally calculate work done in lifting an object of 100 kilogram to a height of 1.5 meter.
As work done W jointly varies as mass m and height h mathematical model for work done can be written.
Where
Using data let's calculate constant of proportionality.
Now calculate work done for lifting 100-kilogram mass to a height of 1.5 meter.
So, work done for given data is 1470 joules.
