Question

PLEASE ANSWER THE 2 QUESTIONS IN BELOW SCREENSHOT

Answer 1

Yes, for example when a person goes to school and then come back to home ,his distance some finite no. but his displacement be zero.

2 min 20sec= 140sec
He moves one round in 40sec,
so he will move 3 and half round in 140sec.
so displacement will be from one corner to opposite corner = √(10×10+10×10)=10√2

Answer 2

Answer:

2 min 20sec= 140sec  

He moves one round in 40sec,

so he will move 3 and half round in 140sec.

so displacement will be from one corner to opposite corner = √(10×10+10×10)=10√2
