Answer 1

Solution :

(i) For motion during the first two seconds , <br> change of velocity

<br> time taken

<br> Thus , acceleration

<br>

<br> (ii) For motion between

second and

second , <br> change of velocity

<br> time taken

<br> Thus , acceleration

<br> (iii) For motion between

sec to

second , change of velocity

<br> time taken

<br> Thus , acceleration
