Question

Paragraph for Question 1, 2 and 3

1. What is the position of particle at t=0 ?
(1) √2 m
(2) √3 m
(3) 1 m
(4) 2m

2. What is the position of particle at t=ls ?
(1) √2 m
(2) √3 m
(3) 1 m
(4) 2 m

3. What is the position of particle at t=0.5s?
(1) √2 m
(2) √3 m
(3) - √3 m
(4) 2 m

Please give the explanation ​

Answer 1

At t=0 it’s position is at under root 3m
Option 2 is correct for 1st question
And at t=1s its again at under root 3m option 2 is correct

Now at t=0.5 means half
Its position is at minus of under root 3 which is option 3 for question 3
