Question

A carpenter leaves several tools on the floor of his workshop when he goes for his lunch break. Sometime later the carpenter returns and sees that one of his coworkers has moved his tools to different shelves on a nearby bookshelf.

Which data would the carpenter need to collect to calculate the amount of work required to lift his tools onto the shelves?

(Choose the correct answers, there is more than one answer)

the height of each shelf

the time it took to move each tool

the amount of force needed to lift each tool

the strength of the person who moved the tools

Answer 1

Step-by-step explanation:

Work done by an object is given in terms of force and displacement as :

`W=Fd`

F is force and d is displacement

In this case, we need to find the data required to calculated the amount of work required to lift his tools onto the shelves. So, for finding the work done, he must know the height of each shelf and the the amount of force needed to lift each tool .

Hence, the correct options are (a) and (c).
