Physics is crazy right?Classical Mechanics Level 1
A man, starting from his home, travels to the mall which is 5 km away to buy veggies for his dinner.
After shopping he returns home, but this time he finds a shortcut which is just 3 km, so he reaches home early. What's the total displacement traversed by the man?
Bonus Question: How much work did the man do? (Consider the frame of reference inside our planet.)
