A chair weighing 60 N is lifted to a height of 0.8 m and then carried 6 m across the room. How much work is done on the chair?

Text Solution

AI Generated Solution

To solve the problem of how much work is done on the chair, we can break it down into two parts: the work done while lifting the chair and the work done while carrying it across the room. ### Step-by-Step Solution: 1. **Identify the Weight of the Chair**: The chair weighs 60 N. This is the force we will use for our calculations. 2. **Determine the Height Lifted**: ...
