A man carries a 10 kg sack of groceries in his arms with a force of 50 N as he walks forward a distance of 10 m. How much work has he done?
To find the work done by the man, we can use the formula:
Work = Force × Distance
Given that the force applied by the man is 50 N and the distance he walks is 10 m, we can substitute these values into the formula:
Work = 50 N × 10 m
Now, let's calculate the work:
Work = 500 N·m or 500 Joules (since 1 N·m = 1 Joule)
So, the man has done 500 Joules of work while carrying the 10 kg sack of groceries for a distance of 10 m.
